When choosing an air purifier, first consider your indoor air quality needs. If you have allergies, you should choose an air purifier designed for allergy relief. These models feature HEPA filters, or High Efficiency Particulate Air filters, which are proven to eliminate 99.97% of common airborne allergens sized at 0.3 microns and larger. These include pollen, dust, dust mites, mold spores, ragweed, and pet dander. HEPA air purifiers are regarded as the most effective air purifiers on the market.

If you suffer from asthma or if your symptoms are triggered by odor and chemical pollutants, you’ll want to consider an asthma air purifier or an odor and chemical air purifier. These air purifiers contain added odor and chemical filtration as well as HEPA filters for allergen particle removal. For pet allergy sufferers, consider HEPA air purifiers, designed to remove pet dander, odors, and hair.

For the pet-parents, air purifiers specifically designed for the elimination of pet dander and pet odors help to efficiently remove the allergy-aggravating pet dander while leaving your home fresh.

What Size Air Purifier Do I Need?

To choose the right size air purifier for your needs, consider the square footage of the room you want to purify. You can calculate the square footage by measuring the length and width of the treatment area in feet and multiplying the 2 numbers together. With this number in hand, find an air purifier with a recommended square foot coverage area that matches your room’s square footage. Look for this information under the air purifier’s specifications.


What Kind of Features Do I Need on My Air Purifier?

After choosing the type and size of air purifier you need, consider whether or not you’d like any special features. Added features can include caster wheels, handles for easy mobility, digital controls, remote controls, multiple fan speeds, filter change indicators, programmable timers, air quality sensors, and more. These features add convenience to operation and give you greater control over your air purifier’s performance.

Where Should I Put My Air Purifier?

In most situations, we recommend that you place your air purifier in your bedroom since that’s where you spend most of your time. Keep in mind that portable air purifiers are designed primarily to purify the air in one room only, so you may need to invest in additional units for other rooms. Alternatively, you can choose a unit that includes caster wheels, handles, and other portability features to make it easier to move it from room to room.

How Much Maintenance and Upkeep is Needed for My Air Purifier?

If you’re using an air purifier with a filter, you should replace the filters at the manufacturer’s recommended filter change intervals to maintain the unit’s high level of pollutant removal. Depending on how many air purifier filters your unit uses, you might need to change them at different times. For example, your air purifier’s HEPA filter might last one year while the activated carbon filter lasts 6 months and the pre-filter (if equipped) lasts 3 months. When shopping for an air purifier, be sure to take the cost and frequency of future filter replacements into consideration.
