I can actually breathe easier

[This review was collected as part of a promotion.] I’ve been using the Phillips Pureprotect Air Purifier for the last week and it’s been a fantastic experience. I didn’t know how bad the air quality was in my home until I started using it. I’m loving the app Phillips Air +, it was easy to download and connect and made using the Purifier much more convenient. My air quality was 20 when I first plugged it in and I could see it improving over the hours with the Air Purifier working hard. Although it was working so well it was very quiet (I couldn’t hear it at all). It worked well in my living/dining room but I look forward to using it in the bedroom to see how it improves the air in a smaller space. I could literally breathe easier after using it for the first day.

Surprising

[This review was collected as part of a promotion.] I wasn’t sure about this product at first as I wasn’t sure if I could gage if it was working or not but this really surprised me. I feel like the air is cleaner in the room especially with little kids. It’s scary to think of how much dust/dirt/pollution. I was vacuuming one day and the lights lit up red to let me know there was a lot of dirt etc in the air. It was great to know it was working. My kids have been less sneezy/coughing which is great. I would recommend this product for anyone with small kids or just to have more purified air to help you sleep better at night.
