The Best Guides to Choosing the Right Air Purifier

If you care about your overall health, you may care about what's in the air you breathe. Even our homes are full of pollutants, which can affect your health and happiness. Daily activities can fill your home with pollutants and allergens.

Choosing the right air purifier can be confusing. There are a lot of charts, studies and certifications on the air purifier. It's crucial to get to the bottom of all the data and make the right decisions. Here is a step-by-step guide to choosing an air purifier.


When considering the use of air purifier, we suggest that you take the following steps in the process of use:

  • Calculate the size of the room using the air purifier.

  • Choose an air purifier and a high enough indoor air purifier.

  • Choose the type of filtering you need to pay special attention to.

  • Make sure you live with the air purifier. Noise and ongoing costs are factors you need to consider.

  • Avoid using air purifiers that cause indoor air pollution. Ozone producing air purifiers should be avoided at all costs.

Know what you're buying?

Although some manufacturers claim that no air purifier will eliminate 100% of pollutants and allergens from the air in your home. The problem is that the air purifier can only clean the air passing through it. Allergens and contaminants attach to carpets, furniture and hard surfaces, waiting to be disturbed back into the air.

When purchasing air purifier, the following points should be considered to ensure the best performance.

  • Where will you use the purifier?

  • Do you have special needs, such as removing pet dander or smoking residue?

  • Compare Cadr rating.

  • Purchase equipment with high efficiency air filter technology.

  • Get a purifier with the lowest noise level possible.

  • Consider the cost of filter replacement and maintenance.

  • Think about whether you need to turn your phone purifier on and off.

The rooms are different in size

Before you go on, you should decide what air purifier your goal is. Most portable independent air purifiers will effectively filter the air in a room. You should make sure that the purifier you buy is large enough to match the size of the room you want to filter. Air purifiers are classified according to their clean air delivery rate (Cadr).

About Cadr - why is it so important?

The larger the Cadr number listed on the air purifier, the more particles the filter removes from the air. Generally, the larger the room, the larger the Cadr number you want. There is no industry standard for Cadr numbers related to room size. Most of the time, the manufacturer will list the recommended room size on the package.

The EPA in their "Guide to Air Cleaners in the Home," makes these recommendations about CADR and room size

Portable Air Cleaner Sizing for Particle Removal:

Room Area in Square Feet 100 200 300 400 500 600
Minimum CADR in CFM 65 130 195 260 325 390

The CADRs are calculated based on an 8-feet ceiling and 5 air changes per hour. If you have higher ceilings, and you need custom air changes per hour, then calculate the minimum required CADR.

What's in the air? What do you want to get rid of?

Contaminants and allergens vary in size, shape and form. Generally speaking, there are two types of pollutants and allergens.

  • particulate

  • Gas

These two types of pollutants require different types of filters. When considering what purifier is best for you, you should consider the type of filter the purifier uses to remove contaminants.

Particles - dust, pollen and smoke

These pollutants include allergens such as pollen and pet dander, as well as smoke residues floating in the air. If dust is a problem in your area, air purifiers can help alleviate the problem as well. In general, the higher the Cadr level and the faster the fan speed, the better the effect of the filter in removing particles.

Some air purifier manufacturers offer special filters for specific contaminants or allergens. Check the package and instructions attached to the air purifier to determine if there is a dedicated filter for your needs.

Gas - we breathe all the time

We live by inhaling gas. Oxygen is the main gas on which we live. However, there are thousands of other gases that can pollute the air in your home, just daily exposure. These residual gases may come from multiple sources:

  • New paint or install new floor coverings. The adhesive used in the paint will release gases that may be allergens or toxic.

  • Older building materials will release formaldehyde and other gases when aging.

  • Plastics used for wall coverings, countertops and furniture release harmful gases.

Generally speaking, the best type of filter for treating gases as pollutants is activated carbon filter. Activated carbon is a good material for absorbing and preserving toxic and harmful gases. The best choice is a combination of activated carbon and high efficiency air filter technology air purifier.

Further understanding of indoor air pollutants and their sources.

Noise level - living with air purifier

Many manufacturers will mark the noise level on the package. If you spend a lot of time in the same room with the air purifier, this can be important. Noise pollution is as annoying as air pollution. Looking for an air purifier with the best noise level and other features you need is an important consideration.

Generally speaking, air purifiers with a noise level of 50 dB are suitable for most living spaces. Modern refrigerators produce about 50 decibels of sound when they run. For most people, this is an almost unobtrusive noise level.

Over purchase price - what is the operating cost?

Buying an air purifier will add another layer to your budget. Running an air purifier 24 hours a day will add extra utility costs to your family budget. We suggest you find an air purifier with Energy Star label“ Energy Star means the device meets stringent EPA standards for energy efficiency.

Keep your air purifier running at maximum efficiency

Another layer of cost, along with your air purifier, is the cost of maintenance. The biggest cost associated with operating the air purifier is to replace the filter. Before buying any air purifier, shop around to determine the cost of replacing the filter. There are many options, and the price range of filter replacement is wide.

Don't buy anything - buyers be careful

There are some types of air purifiers that you should avoid. One type is not recommended at all and may even reduce the air quality of the room.

  • Avoid ozone producing air purifiers - some air purifiers, especially those using electrostatic precipitators, ionizers or ultraviolet lamps, produce ozone. Ozone is a known lung irritant. If someone in your family has lung disease, these types of air purifiers may cause more problems than solve them.

  • Choosing an air purifier is UIL listed - using any electrical equipment without UIL listed is dangerous. Untested and unlisted products increase the possibility of electrical fires.

  • Check whether there is a certified Cadr level on the package - a reputable manufacturer will label the package to indicate the Cadr level tested by a certified laboratory. If there is no such label on the package, the quality of the air purifier may be in doubt.

Make a choice - meet your needs

Finding the right air purifier to meet your needs is not necessarily an overwhelming experience. Knowing what you need in your air purifier is the main factor in deciding which air purifier best suits your needs. Following our step-by-step advice makes the process simpler and simpler.
