Blueair HealthProtect™ 7740i Air Purifier Replacement SmartFilter
Estimated delivery on or before
Description
The SmartFilter comprises one particle filter layer and one active carbon filter layer. The activated carbon in the SmartFilter removes gas, odours, smoke, VOCs, exhaust, smog, and chemicals from the air. The two parts of the SmartFilter are attached at the top, so when removing it, you can fold it over like a booklet to keep dust and pollutants from escaping. The built-in intelligent chip tracks the use of the filter and notifies you through the Blueair app when it is time to replace it. The SmartFilter must be replaced every 6 to 12 months, depending on your environment.

I bought Briiv 2 for my child's allergies.
I bought Briiv 2 for my child's allergies. Usually in their room but we use it in other rooms too. A 1hr boost quickly improves the air; we use the quiet low setting in our child's room overnight, works well. App isn't great, took a while figuring how to manually operate (simple now we know!) but happy with it. Aerify customer service was very good.
Fantastic product
Fantastic product. Works well absorbing room moisture. We have an aerify dehumidifier in both our bathroom and kitchen. Need to replace refill every couple of months.
Love this product. Works well.

De Humidifier
Great unit, second one I have bought. Keeping condensation at bay to drying clothes it works brilliantly, and also with the air purifier outside my daughter’s room who suffers from mild asthma! This has helped loads and not expensive to run.

Easy to use, good value
I bought this after reading reviews by clean air experts. It is easy to use and set up although you do need to make sure it has a regular airing to make sure recalibration is correct. Very handy and is influencing behaviour change (e.g opening windows more or installing HEPA filters) where it shows worse than expected air quality.

Compact monitor for on the go!
I've been using the monitor for a couple of weeks, and it's been an absolute game-changer, especially for someone like me who's constantly on the move. Its compact design is the first thing that caught my eye – it's so easy to carry around, making it a perfect fit for my travels.
One of the most practical uses I've found is in checking air quality in different cafes and coworking spaces. You'd be surprised at the variations – I even stumbled upon a cafe with a CO2 reading of 2000ppm+ Knowing the air quality in real-time helps me choose the best spots to work or relax, ensuring I'm always in a healthy environment.
But it's not just about outdoor spaces. This little device has been a revelation in understanding and improving the air quality where I sleep. Monitoring CO2 levels has led me to make simple yet effective changes, like keeping a window open, which I believe has significantly improved my sleep quality.
In short its an affordable tool that keeps me aware and proactive about the air quality around me, whether I'm at home, in a cafe, or halfway across the world.

Aerify
Hi I am surprised with the amount of moisture that the Aerify unit absorbes not in bathroom or kitchen
I have 2 units
I am very pleased with the results
Aerify good one
Amazing little air purifier
I have severe dust and pollen allergies. This little air purifier is small but mighty and has freed me from having to be locked away in the house to avoid the allergens. I take it everywhere now, as it is portable and really works to purify the air around me. I would recommend to anyone that has environmental allergies.
Boneco fan.
Absolutely brilliant it does what it said it would do . Thanks agian.
Great products, good prices and excellent, fast service
Very happy with the price for the Blue 3210 filter, and was impressed that it arrived the next day! Will definitely order again.

Perfect the Window Sill
Until, I saw this product, I thought small dehumidifiers were the plastic ones you brought in supermarkets and I needed a more sturdy one that lasted longer and this 'fitted the bill'. I brought the pink one which added to colour t my new decorated bedroom and finger crossed it is doing its job. The 'You Tube' video which shows you how set up is great and was the push for me to buy it. Thank you
