What makes the best air purifiers so good?

The best air purifiers generally contain a top of the range High Efficiency Particulate Absorbing (HEPA) Filter, which removes 99.97% of pollutants down to 0.3 microns in size from your indoor air. For some context, pet dander is generally 5 to 10 microns in size, a piece of dust mite feces is 10 to 40 microns and particles of pollen tend to be 10 to 200 microns in size. With this in mind, an air purifier with a HEPA filter is capable of removing almost all of the major allergens from the air. 

A good air purifier will have multiple layers of filtration, including a charcoal filter for odors and larger particulates to help the HEPA filter to last longer. Many often have UV lights to help destroy bacteria and viruses once they have been trapped within the air purifier.

Should you buy an air purifier during Amazon Prime Day?

Prime Day is a great time to buy an air purifier, with great savings across Amazon on these bigger ticket items. Amazon Prime Day runs from 11-12 July this year, and you can still sign up for a free trial to access discounts. 

It's worth grabbing home health deals while you can, as the cost of living continues to increase. This slashing of prices just before the festive season can help you save money on bigger ticket items, like the Dyson Purifier Cool.

 So, if you're in the market for an air purifier, or want to give an air purifier a go to see if it improves your respiratory symptoms, it's a brilliant time to buy. Amazon Prime Day gives you an extra opportunity to save money that non-prime members might not know about.

Although Prime Day hasn't quite hit the rush of Black Friday and Cyber Monday sales, it's still a good chance to save some of your hard earned pennies, although deals might not be as good as they are during bigger sales. 

You might find products stay in stock for longer too, because of the smaller scale of this event, but bear in mind that increased demand can take its toll on manufacturing and production, so it's best not to wait around if you've found something you really want, as it could be sell out fast.
