Review on Holmes AER1 Total Filter HAPF30AT by Jimmie Trotto

I use this next to a litter box which is a challenge for an air purifier. I usually use a vacuum cleaner in "Blow" mode to clean the filter and the unit every 3-4 months. This allows me to double the life of the filter and free the device from dust. Unfortunately, with this filter, most of the dust will pass through the filter and into the instrument, evidenced by debris clouds. the dust that is released when I blow through the device with the filter removed. But it's much better than nothing. I used the tray in the room for about a month and everything was covered in a thin layer of dust - thus reducing a TON of dust that would be everywhere. It's not perfect, but don't expect that from this filter. This is a 3 star filter and will never get better. If you want a 5-star filter, you must buy a TRUE HEPA filter.
