By focusing on the following key factors, you can easily find a home air purifier that perfectly fits your space and helps you breathe easier.
Not all air purifiers are created equal, so you need to choose a unit that can handle the size of the room you hope to purify. Make sure to measure the square footage of the room and consider how bed size might influence available space.
Also, try to pick a machine that can clear the air in the shortest amount of time. Top machines can clear 1,000 sq. ft. in an hour, and for smaller rooms, the time factor should be considerably less.
During these times of inflation, the budget is always a concern, yet it is important to make sure that the air purifier you buy has certain important features like HEPA and activated carbon filtration. A quiet sleep mode and at least one certification are also key elements. Depending on your room size, a good air purifier can be purchased for as little as $99.
The only real maintenance for the best air purifier is changing the filters periodically. Most manufacturers recommend changing HEPA filters every 6 to 12 months, depending on usage.
Some units also have washable pre-filters, which will contribute to the life of the HEPA filter, so you’ll need to change it less frequently. These washable pre-filters can often be cleaned in washing machines, making maintenance even easier.
Most HEPA air purifiers come in neutral colors with simple, contemporary designs that will blend in with most decor. Just as you carefully select mattresses for comfort and style to fit your bedroom, you can find an air purifier that complements your space without being an eyesore.
