How to Choose the top air purifier for you home?

How Much Square Footage Does it Cover?

When shopping for one of these products, you need to pay attention to its square footage rating, which is the amount of square footage it can cover. The manufacturer should list this information clearly on the box or in the product description. You’ll find a range of between 50 square feet up to hundreds of square feet.

Smaller models are best for using in a home office or a nursery. Those that cover 400 to 600 square feet will work well in a larger room or a more open space like a home with an open layout. If you need more coverage, you’ll need to purchase multiple units or find one designed for the whole home.

Does it Come with a HEPA Filter?

The best filters available for these products are HEPA filters. HEPA filters remove more particles from the air and will work on particles of smaller sizes. Some of the newer products have a HEPA filter and one or more made from other materials.

One example is an activated carbon filter. Also called activated charcoal filters, these products use charcoal or carbon to actually absorb any bad odors that pass through. Some companies include filters with baking soda inside that can aggravate allergy symptoms in some people.

Other models use a form of light filtering such as UV-C light. This type of technology uses natural and artificial light to actually kill germs and bacteria. Some of the top models for sale use at least two different types of filters.

Will it Remove All Particles?

Manufacturers use a measurement called micron to describe the size of the particles that their products can remove from the air. Some of the smaller and cheaper models will only work on larger particles like those you can see floating through your home.

Top models now work on particles as small as 0.01 microns in size. While you may not need one that targets those smaller particles, the model you buy should work on microns of at least 0.3 in size. This ensures that it will work on pet dander and other hazards that you cannot see.

How Does it Operate?

Not all models on the market today come with an electric cord that you use with an outlet. Many now come with an internal rechargeable battery that you can charge with an outlet or a USB cord. When choosing a rechargeable option, find out how long the battery will last as some will only run for a few days or less before you need to charge the battery.
