Portable room air purifiers are designed to filter the air in a single room. They're separate from whole-house air purifier systems and air filters, which are integrated into a home's heating, ventilating, and air conditioning system and designed to clean the air in the entire house.

Think of a room air purifier as a supplemental unit, like a space heater in the context of a whole-house heating system, explains Misha Kollontai, who oversees testing of air purifiers at Consumer Reports. While your house might feel sufficiently warm, you might have a particularly drafty room with old, poorly sealed windows; placing a space heater there would make the room more comfortable. Similarly, he says, "a whole-house system will work at filtering all the air that passes through it via the HVAC system. But if you're sitting next to a fireplace in the living room for extended periods of time, a room air purifier there may not be a bad idea." A room air purifier may be worth it too, say, in a bedroom, if you sleep with your pet.
Different air purifiers work using a range of technologies. A few are helpful. Others are ineffective, or even potentially harmful to your health.
Mechanical filters: These purifiers use fans to force air through a dense web of fine fibers that trap particles. Filters with very fine mesh are called HEPA filters. While they work on microscopic particles, they can also remove larger particles (including dust, pollen, and some mold spores) when they're suspended in the air. (Some filters are labeled 'HEPA-type' or 'HEPA-like''these have not been certified to meet the requirements of a true HEPA filter but may still perform adequately in our tests.) Mechanical filters don't help with gases or odors. And they can be expensive to maintain. Mechanical filters need to be replaced every six to 12 months; they can cost upward of $200 per filter but typically cost no more than $80.
Activated carbon filters: Unlike mechanical filters, these filters use activated carbon to capture certain types of gases, including some odor-causing molecules. But they're not particularly effective against formaldehyde, ammonia, or nitrogen oxide. Because activated carbon filters don't combat particles, many air purifiers will have both an activated carbon filter and a mechanical filter. Activated carbon filters get saturated faster than mechanical filters, though, and require replacement more frequently'every three months, as opposed to every six to 12 months for mechanical filters. Make sure to budget for replacements accordingly: Activated carbon filters usually cost up to $50 each.
Ozone generators: These machines produce ozone, a molecule that can react with certain pollutants to alter their chemical composition. This can result in dangerous indoor air quality, and CR does not recommend these types of air purifiers. Makers of ozone generators often claim that the devices emit safe levels of ozone, but in the past, our tests found that even at low settings, some ozone generators quickly exceeded the Food and Drug Administration's limit of 0.05 parts per million for medical devices. Plus, studies reviewed by the EPA have shown that low levels of ozone'the chief ingredient of smog'don't effectively destroy indoor pollutants. Research also shows that ozone has been linked to decreased lung function and increased risks of throat irritation, coughing, chest pain, and lung tissue inflammation. Ozone exposure might also worsen asthma, emphysema, and bronchitis.
Electrostatic precipitators and ionizers: In these electronic models, particles in the air become charged so that they stick'magnet-like'to plates on the machine or to nearby surfaces. CR doesn't typically test electronic air purifiers nor recommend them because they can produce ozone.
Ultraviolet germicidal irradiation (UVGI): Some manufacturers claim that their air purifiers kill airborne viruses, bacteria, and fungal spores with UV lamps. But they might miss certain bacteria and mold spores that are resistant to UV radiation. To work, the UV light must be powerful enough and the exposure must last long enough'minutes to hours, rather than the few seconds typical of most UVGI air purifiers'to be effective. CR does not test UVGI technology, though some mechanical air purifiers we test may have the added function.
Photocatalytic oxidation (PCO): Some air purifiers use ultraviolet radiation and a photocatalyst, such as titanium dioxide, to produce hydroxyl radicals that oxidize gaseous pollutants. Depending on the pollutant, this reaction can generate harmful byproducts, such as ozone, formaldehyde, nitrogen dioxide, and carbon monoxide. CR does not currently test air purifiers with PCO technology. There have been few field investigations exploring the effectiveness of PCO air purifiers, but one laboratory study, conducted by researchers at Syracuse University in New York, reported that the devices did not effectively remove any of the VOCs typically found in indoor air.
Photoelectrochemical oxidation (PECO): This variant of PCO emerged in from the manufacturer Molekule. The Molekule Air purifier did not score well in our tests for dust, smoke, and pollen removal. Since then we've also tested the more expensive Molekule Air Pro, which performed better at removing contaminants on its highest setting but did not impress in CR's other air-purifier test categories, nor did it rate well in our CR member survey.
To see how well these machines clean the air, we inject smoke and dust into a sealed chamber and use a particle counter to measure the change in air particle concentration in the room as the test model runs for 15 minutes.
We test using particles as small as 0.1 micrometer and up to 1 micrometer, a range that includes dust mite allergens, cat allergens, smog, smoke, and atmospheric dust. We don't measure for particles larger than 1 micrometer, such as pollen, because any air purifier that scores well in our tests should also be able to handle larger airborne particles.
Because most air purifiers have several speed settings, we test for dust and smoke removal both on the highest speed and at a lower speed that runs at a noise level no louder than 50 decibels. We also measure noise levels at every speed setting that a machine has. And because air purifiers must be running at all hours to be effective, we calculate annual operating costs, which include filter replacements and energy use to run the machine 24 hours a day for an entire year.
Owner satisfaction and reliability ratings are also included in a model's Overall Score. These ratings are based on Consumer Reports' Summer Survey of 8,377 air purifiers purchased between and . The very best models in our tests effectively sanitize the air of dust, smoke, and pollen, and receive high marks for predicted reliability and owner satisfaction.
CR recommends more than three dozen models in our air purifier ratings, and most use a HEPA filter; a vast majority also have carbon filters to help assist in the removal of odors. These models meet Consumer Reports' criteria for safety, performance, value, and reliability. For more information, read our article on the best and worst air purifiers of the year.
Cost of replacement filters: As a general rule, you should replace filters (or clean those that can be vacuumed) every six to 12 months if they are pleated and every three months for activated carbon filters. Most of the units we test have an indicator light that lets you know when to change (or clean) the filter. The costs of filters vary widely: In our tests of large air purifiers, they range from $20 to more than $200. Filters with odor-removing carbon can cost as much as $50.
Clear Air Delivery Rate (CADR): This value is provided by air purifiers tested by the Association of Home Appliance Manufacturers. Many air purifiers have undergone AHAM's voluntary certification program, which provides room size guidelines along with the CADR on its AHAM Verifide seal. The CADR reflects, in cubic feet per minute, the volume of clean air that an air purifier produces on its highest speed setting. For example, a purifier with a CADR of 250 for dust particles reduces particle levels of dust to the same concentration that would be achieved by adding 250 cubic feet of clean air each minute. The higher the CADR, the faster and more efficient the air purifier is. Room air purifiers with HEPA filters often achieve the highest CADR. There are different CADR ratings for removing tobacco smoke, dust, and pollen. Focus on the CADR for your main pollutant of concern. For instance, if you live with a smoker, choose an air purifier that has a high CADR for tobacco smoke.
Energy Star certification: Air purifiers must run around the clock to be effective, so you should factor in the energy cost when you shop. Energy Star certified purifiers are 40 percent more energy-efficient than standard models.
Room size: If an air purifier has an AHAM Verifide seal, you can trust that the unit can handle the suggested room size listed on the seal. Be wary about manufacturers' claims, though. We have tested many air purifiers that are not suitable for their claimed room sizes. You can check our ratings to see what room-size range we suggest for each model based on our test results. Also, consider sizing up: Most models suitable for large rooms (350 square feet and larger) can also work well for smaller rooms at lower speeds. Lower speeds tend to be quieter'which is nice for when you're watching TV or sleeping.
Noise: Judge an air purifier not just by how well it performs but also by how well you'll be able to live with it. Because these machines should always be running, ideally they should also be quiet. (For reference, a noise rating around 50 decibels is roughly equal to the hum of a refrigerator.) You may be able to find a model's decibel levels on its packaging or website listing before you buy it. Or check our air purifier ratings; we rate models on noise levels at both high- and low-speed settings.
Clean or replace filters regularly. An air purifier can't run efficiently if it has a dirty filter. Typically, you should replace filters (or clean those that can be vacuumed) every six to 12 months for pleated filters and every three months for activated carbon filters.
Place it wisely. If you have just one unit, put it in the room where you spend the most time. For most people, that's the bedroom. (Some units can be heavy and clunky to move around, so if you want an air purifier in multiple rooms, you may want to buy a unit for each room.) Make sure to place the air purifier in a spot where nothing can obstruct airflow'away from curtains, for instance.
Adjust the speed. To avoid noise disruptions, we suggest running the unit on its high-speed setting when you're not in the room and turning it down to low when you're nearby. Or buy an air purifier certified for a larger area so that you can run it on a low speed and still have it work effectively.
It can be fun to go to Lowes or Home Depot Saturday morning and work on a project for your home, but it is probably not the best place to buy air filters. You need to replace your filters on a regular basis to protect your HVAC equipment and to protect your home's air quality.

Nominal Filter Size: The main cause for wrongly bought filters is the nominal size. This size refers to the dimensions on a filter's label, but they are often rounded numbers and not the exact measurements of that filter. For example, a nominal size could be 16x20x1. These dimensions are a rounded value of the filter's actual measurements. The actual measurements on this filter could be 15.5x19.5x.75, but that may vary by brand and manufacturer. To make sure you have the right size filter, especially if you're changing to a different brand, it is important to confirm the real size of your existing filter. When you purchase filters from the internet, in most cases you can find the nominal size within the product title. When searching for a filter, typically people enter the nominal size. It could be "furnace filter 20x25x1" or perhaps "20x25x4 furnace filter," and even "20 25 1 air filter," but always confirm the actual size to ensure it's also a match for your house air filters.
The most common AC filter sizes and furnace filter sizes are the 16x20x1 air filter, 20x20x1 air filter, the 16x25x1 air filter and the furnace filter 20x25x1. All of these ac filter sizes can be found in the air filter size chart. The chart is a furnace filter size finder just click on the filter sizes and you will see purchase options. Click on the air filter 16x20x1 to see merv 8 filters, merv 11 filters and merv 13 filters available in the ac filter sizes.
Some people wonder is a 2 inch filter better than a 1 inch air filter? Well when is comes to 1 inch vs 2 inch furnace filters you should use the filter your system is designed to use. A 1 inch AC filter may have to be changed more frequently but will so the same job. Deeper pleated filters can last longer because they have more media. So the same would go for 4 inch vs 1 inch furnace filters. A 4 inch furnace filter will last a longer time than a 1 inch. The return grill space or the furnace must be designed to have the deeper filter to be used. Many commercial spaces use 2 inch filters or 4 inch filters to help reduce maintenance cost of replacing filter. From a filtration stand point a 20x25x1 air filter merv 13 and a 20x25x4 MERV 13 furnace filter will both have the same performance of filtration.
The actual size, as you may have guessed, is the actual dimensions of the filter by length, width and thickness. This size is usually on the filter right below the Nominal size and is usually labeled as the actual size. When you are buying a filter online the actual size is sometimes in the product bullet point or the product description. If your filter does not have actual dimensions on the outside of the filter, you can measure you filter to get the correct dimensions. Some brands have a foam gasket on the outside of the filter, in this case you will want to make sure you have a compatible actual size and that it also has the foam to insure a snug fit. Check to see if the filter list compatible brands and model numbers. These are usually in the filter descriptions and bullets of the filter detail page. On Amazon you can usually find this information farther down the product page below the fold or click the link for additional product details.
You can proactively clean the air and surfaces in your home by adding an In Duct Air Purifier that creates supercharged particles. This is the same compound created by thunderstorms and waterfalls in nature and helps purify the air. Aerosolized ions are effective in reducing bacteria, viruses, odors, and other contaminants that exist in the air you breathe inside your home. This creates charged particles which will attract to other particle in the air for better filtration when using electrostatic filters. Check out the Iwave-R. Learn more about how these air purifiers work to purifier the air and surfaces in your home.
When considering the air quality in your home, you should consider an air filter with highest level of efficiency that is compatible with your HVAC system. Minimum efficiency reporting value, known as the MERV rating, is a measurement scale designed in by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to rate the effectiveness of air filters.
Comparing MERV ratings is a good way to begin to comparing filters. A Pleated filter with a rating of at least MERV 8 is better for airflow which is going to help your HVAC system operate more efficiently while still protecting your air quality. Home Air Filters have MERV ratings that range from 0 to 16. Most new homes can support an air filter with a MERV rating from 8 to 13 filters, but MERV 15 and 16 filters require a system that can support the necessary air flow.
Depending on your HVAC sytems you may have return vent filters or a whole house filter. Vent filters, as the 20x20x1 air filter pictured are more straight forward to find the actual size and correct replacement.
The image above is from an Atomic Filters 20x20x1 Furnace Filter MERV 13 product listing. In addition to the filter having the Nominal size and actual size on the product image, the product title list the nominal size. The actual size for the filter is listed in the bullet points. Once you know what information to look for, making the purchase decision straight forward.

Whole house furnace filters often have compatible models across brands, but you need to insure that the replacement filter is compatible with your systems filter.This is best done by checking the product description to make sure your current filter model is listed.
You can usually find the proper replacement filter model in your HVAC user manual. In the Amazon listing pictured for this Lennox Filter, you can see all of the information you would need to make the correct purchase.
#1 Shows the Nominal Size of the Filter in product title along with the Brand.
#2 Shows the Lennox Model number X for this furnace filter.
#3 shows other brands compatible model numbers this filter can replace.
#4 shows additional details on the filter including the actual size of the filter.
You can find the part number or the size on the side of the filter. Filters are measured by Nominal size which is a rounded number that varies by brand so many filters have the part number for each brand they are compatible with listed. The Lennox filter below shows it Part number X and the Honeywell part numbers, FC100A and FC35A, that this filter can replace.
Using the wrong air filter over time could end up damaging the heating and cooling system itself. By reducing your systems efficiency, you could notice higher utility bills. When you use the wrong size air filter, or you install it incorrectly, the filter can't effectively prevent dust from accumulating on the system's coils motors and blowers. You'll end up with a dirty furnace that can't properly perform, and all of that debris could end up harming the system's internal components.
While you may think that using a more efficient filter with a MERV rating from 15 to 16 would be the smart option for allergy suffers and improved air quality, not every system is designed to work with these highly rated filters. If your system isn't compatible, these filters will drastically restrict airflow. You can still have a high-efficiency filter, but make sure it's one that is designed to work with your HVAC system.
You can still have a high-efficiency filter, but make sure it's one that is designed to work with your HVAC system.
Using an air filter with too high of a MERV for your system can have similar effect of a clogged air filter, if a filter becomes clogged, airflow will be reduced, which causes the fan motor to work harder. This means more energy is used, which will increase your utility bill. Eventually the fan motor can burn out, resulting in overheating and failure of the entire system. Overheating can cause a heat build up around the heat exchanger in the winter which can cause the heat exchanger to crack. A cracked heat exchanger is a serious issue and needs to be replaced immediately to prevent system failure, fire or the release of carbon monoxide gas into the home.
Having Dirty filters can allow components within the HVAC system to get dirty. This causes problems such as dust and debris on cooling coils, which can lead to freezing on the evaporator coils. Frozen coils block airflow, reducing the system's ability to maintain indoor climate control which causes the system to work harder with less efficiency increasing your energy bill. Left unchecked, the system will fail and requiring a costly replacement.
Dirty air filters can lead to excess dirt that will end up in your ductwork, and you'll need to have the ducts cleaned more frequently. Dirty ducts compromise air quality and some of the dirt can end up back in the HVAC system.
Once you find the right air filter for your systems, consider getting a subscription and make it automatic. This will ensure your HVAC system is always protected from the most preventable causes of failure and you will have one less thing to remember. Companies often offer a discount on subscriptions saving you even more money.

It is easier than ever to Securely purchase items on line then ever before in History. We have many options to use such as Apple pay where we can make a purchase and check out right on our phones with out having to enter any information. Apple Pay and other payments providers allow you to use stored payment information and stored shipping addresses. Although this is very convenient, it can sometimes lead to having the wrong shipping address on orders if we do not keep that information updated when we move. America is a much more transient population than a generation ago, so if you have moved recently make sure to update all of you payment account shipping addresses before using them to place orders online.
You will usually get a notice when your order is placed, when it ships and when it is delivered. We place so many orders online it is often hard to keep track of everything. With our emails so cluttered, we can easily miss these notifications. Although most orders arrive in 2 to 6 days anywhere in the county, sometimes weather and other factors can also cause delays. Generally if you have not received your filters in 7 to 10 days, it is time to call or to check on your order. The item may have been misdelivered or lost by the delivery service. The sooner you can check on it the better. Many delivery services such as Fedex and UPS have a time limit on when they can run a trace or enter a claim.
Often times, we order air filters ahead of time to always have a backup when it is time to replace the filter. Many filter company's have had supply chain issues making it hard to finds certain filters so it is a good idea to have your filters before you need them. With many filters having similar items numbers it can be easily to order the wrong part. Since many companys have time limits on returns, it is a good idea to check the items part number as soon as it arrives, but do not open the item if it is factory sealed, this could void your return.
It is best to check the item number before opening any sealed parts. Many part numbers are very similar and ordering mistakes happen frequently. Opening the item or writing an installation day on an item may void the return rights as the item can no longer be sold as new even if it was not used. You would not accept a filter that had writing on it or was not in the manufacturer writing if it was supposed to be new, would you?
This can usually be avoided by double checking the item before you order, but occasionally the wrong item may also be sent, so it is a good idea to double check all of the number before ripping open factory packaging such as sealed plastic shrink wrap on an item or writing an installation date on the side of a filter.
So now that you know best place to buy air filters and how to get the right filter,
How are you going to Buy You Air Filters?
When looking for the correct home air filter here are several questions you might have.
1. What are the Best home air filters?
The best home air filters is a relative question. You should get the highest MERV rated filter your HVAC system will support it you want the best air quality in your home. Newer Modern HVAC systems should all support at least a pleated MERV 8 rated filter which is around the minimum level you would want to protect your homes air quality. MERV 11 to 13 filters is recommended for allergy sufferers. Superior systems from Carrier and Lennox offer some of the best residential filters available at MERV 15 and 16 respectively.
2. What do air filters do in a house?
The primary function of an air filters is to protect your HVAC equipment from damage that can occur from dust and debris accumulating on the coils.This can have an effect on the efficiency of your system causing higher energy bills and a shorter system life.
Newer systems air filters are not just focused on protecting the equipment but improving the air quality in your home which is one of the number one health concerns listed by the EPA, CDC and American Lung Association.
3. How Often do you change air filters in your home?
How often you change your home air filters depends on the type of air filter you have in your house and environmental conditions such as smoke, dust or construction.
Generally here are some guides but it can vary by manufacturer.
1 inch flat air filter - change every 30 days
1 inch pleated air filter- change every 2 to 3 months
Whole house filters - change 6 to 12 months ( more frequent change for desert areas and High humidity tropical areas).
4. How much is an air filter for a house?
Cost on filters may depend on the size of the filters but here are some ballpark prices.
1 inch flat green fiberglass filters which are considered cheap air filters can cost less than $1 but may have no MERV rating meaning they do not protect the air quality.
1 inches pleated MERV 8 filters can be as little as $4.50 if bought in bulk such as a case of 6 filters but the cost is dependent on the size of the filter.
Whole House filters vary in price by manufacture and can range from $25 to well over $100.
