However, clean air comes at a price. Depending on the size of the existing space, the best air purifier is reliant on the number of square feet, large rooms, and type of air filter in a house.

In most homes, an air purifier is particularly useful in eradicating airborne contaminants, including pet dander, tobacco smoke, dust mites, and even mold spores.

Yet, large-room air purifiers take it a step further by eliminating harmful airborne particles in areas of over 1000 square feet. This ensures that every corner of the room has consistent air cleaning that keeps indoor air clean and fresh. For many, clean air is no longer a luxury but a necessity where air purifiers remove toxins with ease.

There is no right answer to this question. It solely depends on your needs and the severity of your allergies. For enclosed spaces above 2000 sq ft, it is recommended to get a good air purifier like the Coway Airmega 400 to cover the entire area.

However, if you are prone to allergies and respiratory issues, it is preferable to have multiple units in one house to ensure you have access to clean, quality air at all times.

The short answer is yes. However, it is essential to highlight that this depends on your preference. For users with severe respiratory issues, multiple units are recommended instead of a single one for cleaner air quality around the clock.


Can one air purifier clean an entire house?


Yes, one air purifier that is designed to meet the square feet of an entire home can purify indoor air quality. This is dependent on the type of air purifier chosen.


How many air purifiers does a home need?


This is reliant on your needs. If your air purifier covers the number of square feet in your home, you are good to go. For severe respiratory symptom sufferers, it would be wise to have one in each room to keep the air clean at all times.
