If you're looking for the best cheap air purifier, we've got you covered right here.

What counts as a 'cheap' air purifier will depend on your budget and circumstances, but generally speaking, more affordable options can be bought for around £150/$150 or less.

This price range is very forgiving compared to some of the best premium air purifiers, which can be considerably more expensive.

When it comes to buying an air purifier, you'll want to keep an eye out for the extent to which purifiers can clean air, and for this, you'll want to look out for CADR ratings, or the clean air delivery rate.

In addition, you should consider your maximum intended room size, and if the air purifier is designed to cover that much space. For huge rooms, you may want to gravitate towards something a bit beefier!

Noise level is something else you'll want to factor in - ideally, you'll want it to be as quiet as possible, and the very best purifiers can get lower than 30dB (decibels).

We've taken a look at what's available on the market today, aligned them with what we think makes a fantastic cheap air purifier, and selected a number of options based on everything from specs to reviews.

So, let’s get to it – here are some recommendations for the best cheap air purifier out there today.
