Review on 🔍 Smilyan 6 Pack HPA300 HEPA Replacement Filter R for Honeywell HPA300 HPA200 HPA100 HPA090 Series Air Purifier - High-Quality Alternative to HRF-R3 HRF-R2 HRF-R1 (6 Hepa + 8 Carbon) by Adam Mazie

According to the description, it matches our device, but it is not correct. Activated carbon filters must be cut to size. However, they are VERY thin. I'm not sure if they work well at all. Hepa filters are slightly smaller so there is space around them that allows the air to bypass the filter entirely, defeating the purpose of the air filter and slowly damaging the unit as it slowly collects dust. Definitely cheaper than Honeywell products but you get what you pay for. I will never buy again. Tired of misleading marketing on Revain
