Now that you’ve taken a look at the 13 best air purifiers to buy, read on to learn more about how to use them. We’ve put together a buying guide to help you find out everything you need to know about air purifiers.

How To Choose The Right Air Purifiers – A Buying Guide

When it comes to buying the best air purifier, you must keep the following things in mind:

1. The size of the room

Depending on how big your office space or any other room in the house is, you can make a pick. Most air purifiers cover an average of up to 160 sq.ft. If your room is smaller, consider picking something compact and lightweight. For larger rooms or areas that are bigger than 360-460 sq.ft., choose a larger air purifier accordingly.

2. Type of filters

There are generally 4 types of air filters. The pre-filter captures large particles before transferring them to the next stage while the HEPA removes the smallest particles, including 0.3 microns, tiny pollen, and more. The third type of filter is an activated carbon filter that eliminates chemicals and organic matter. The UV filter is designed to remove bacteria but is considered inefficient as they travel through light quickly and may not be effectively terminated. While the most common type is a HEPA filter that comes with a pre-filter, the most effective one combines all 3 – a pre-filter, HEPA filter, and an activated carbon filter.

3. Maintenance

An air-purifying filter needs constant maintenance, and you should pick one that suits your needs and convenience. HEPA filters need changing anywhere between 12-18 months, whereas activated charcoal filters need changing 3-6 months. Pre-filters need to be changed every 30 days, but a UV filter requires no maintenance at all.

4. Features

Today, air purifiers are technologically advanced and can do many things with the touch of a button. They come with a voice assistant, can be paired to your smartphone and can be operated via Bluetooth, smart buttons with touch sensitivity, to name a few. But there are basic models too, that do the bare minimum. If you’re tech-savvy and would love the features mentioned above, look out for a smart air purifier.

Frequently Asked Questions

1. What is the difference between air purifiers, air filters, and air cleaners?

An air purifier is an air sanitizing device that emits substances like negative ions, ozone or utilizes heat to improve air quality and reduce contaminants like viruses, allergens, and other pollutants. On the other hand, air cleaners filter out the harmful particles rather than sanitize them to provide cleaner air. Air purifiers are less expensive than air cleaners, and most feature a silent operation mode. An air filter is made of fibrous or porous materials and traps unwanted particles.

2. How often do you need to change an air purifier’s filter?

It depends on the type of filter used. HEPA filters are changed annually, whereas pre-filters are changed every 30 days, and carbon filters last anywhere between 3 to 6 months.
