The air we breathe should always be clean but in today’s polluted world, it never is, even at home.
Your home and office’s air is full of pollutants, pollens, mold, dust, germs and more and even volatile organic compounds (VOCs) which can cause cancer.
By investing in a smart air purifier (or two) you can help to ensure that the air you breathe is truly clean and the smart functionality will ensure you don’t waste energy purifying air when you don’t need it.
How We Chose The Best Smart Air Purifiers
There are, of course, a lot of different features in smart air purifiers but we wanted to focus on the things that mattered:
- Decent sized room coverage – you don’t want to spend a fortune on air purification and that means, a purifier should ensure that a decent sized room stays healthy without the need for extra purifiers
- Energy star certification – you certainly don’t want to use more energy than necessary to keep the air clean
- Smartphone app compatible – this is a “nice to have” feature which makes using a smart air purifier easy when it’s available, if you don’t need smart features – you can check out these awesome air purifiers too
- HEPA certified filter – the filter needs to actually clean the air and the HEPA standard is a great way to ensure that it does

A smart air purifier makes a huge difference to the quality of the air that you breathe.
