Why Blueair is Healf
Blueair uses a four-layer filtration system with HEPASilent™ technology that combines electrostatic and mechanical filtration to remove 99.97 per cent of airborne pollutants such as pollen, dust, and smoke. This approach captures tiny particles faster and more quietly than traditional HEPA systems, and it builds on technology first developed by the brand’s founder and now trusted in over 60 countries. All Blueair air purifiers meet CARB standards and operate within strict ozone limits, with independent testing at Intertek confirming emissions far below required thresholds. Several models also hold Zero Ozone Verification, which confirms ozone levels of 5 parts per billion or less. This proven, carefully tested system helps you breathe cleaner air with confidence every day.

Blueair was founded in 1996 in Stockholm by Bengt Rittri, driven by a simple goal: to ensure his children could breathe the same clean air indoors as they did in the Swedish archipelago. With a deep commitment to environmental responsibility, Rittri built Blueair into a global brand focused on healthier indoor living. The brand develops high-performance air purifiers using precision-engineered filtration technologies designed to capture airborne particles, allergens, and pollutants efficiently and reliably. Each system reflects a science-led approach, combining smart design with carefully tested components to deliver consistent air quality. Through this commitment to clean, effective solutions, Blueair helps create healthier homes so you can breathe easier every day.

    Amazing

    Amazing!!! I unpacked on Sunday and the unit has been programmed and runs like a whisper. Truly amazed at the app. Shows real time data and pollution inside and outside via WiFi. Simple to operate and maintain. A very powerful tool that fits anywhere. Well done I’m looking forward to restful evenings and less asthma symptoms Thank you Healf ❤️

    Bought on our doctor’s recommendation

    Bought on our doctor’s recommendation for allergies and it seems to be helping. We use it in our bedroom and are definitely less blocked up in the morning.

    I wanted to love this

    I wanted to love this but for the price I’m not so sure. It’s been a bit temperamental and I havn’t really noticed much of a difference in air quality and dust.

The best wellbeing website…

The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.

Alex

Amazing!

Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!

Janet

Great products, service, and customer support

Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf

It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
