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 Ben Liu

I am very happy with this replacement head. My 5 year old has multiple airborne allergies to grasses, pollen and ragweed. Now that they're all up in the air, we can't put them in a bubble. The allergist suggested Claritin and Nazacort, which helped but were not suitable for long-term use. It's awesome to use this air purifier in her room at night. She had a cough that would not go away and was very stuffy. After 1 week of daily nightly use it was gone. Love it. 2 refills and carbon filter, great price.
