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.

Dear Kate,

Thank you for your review of the Smart Air 3-in-1 Monitor. We're pleased to hear it's easy to use and offers good value. Your diligence in recalibration is noted. It's great to see that the monitor influencing positive changes in your habits for better air quality.

Feel free to reach out if you have any questions.

Best regards,

Aerify team
