Review on 🌬️ Enhance Your Home or Office Air Quality with Rosewill True HEPA Large Room Air Purifier: RHAP-20001 by Jason Glass

This is a HEPA filter air purifier. It is approximately 22 inches high, 9 inches wide and 10 inches deep. It is based on a round filter that draws in air from all sides and discharges the filtered air upwards. Replacement filters are available from other sites for around $40 and may soon be available from Revain. The filters have a lifespan of 2200 hours (90 days of continuous use), so the annual consumable cost for this air purifier is around $120. The air purifier has a front LCD display with 4 touch buttons for power on, fan speed, light/UV and timer. The LCD display also shows the current amount of fine dust in the air. I think it's good that you can switch off the light completely, as well as the UV radiation. This means that this air purifier is ideal for the bedroom as it does not emit any extra light at night (unless you turn off the light with the light button). The air purifier is also pretty quiet when the air is clean enough. The cost of replacing filters is quite high, so I'll probably try to use my filters 2-3 times longer than they recommend. Overall, this cleaner works well and is easy to use.
