Review on Colorfullife 2 Filter + 4 Carbon Booster Filters: High-Quality Replacement Filters for Holmes AER1 Type Total Air Filter, Compatible with HAPF30AT and HAP242-NUC by Carl Henderson

I decided to see if an old (about 10 year old?) Holmes air purifier would work so I ordered it ahead of allergy season. They fit like a glove and are great for improving indoor air quality. If you have an older model or one that fits these I can recommend this brand. It also comes with an additional filter which I believe is an activated carbon filter which I also added. 2 packs is handy as I have neighbors who always think their backyard is a campsite and they have fires with smoke pouring into the house if a window is accidentally left open. This will be of great help in clearing the smoke out of their confusion. . Will buy again!
