Review on 🌬️ LEVOIT Air Purifier Replacement Filters: H13 True HEPA & High-Efficiency Activated Carbon Filters - LV-H134-RF, 1 Pack, 3-in-1, White by Tre Boyer

They are very expensive, no pre-filter to vacuum, only 1 month for $80 ! They're up $20 in the last month since I bought the air filter myself. I've bought several air filters and while the small square filters work well, the large tower filters take about a month and a half to get through the filters making them very expensive. The "pre-filter" mentioned is not a real pre-filter that can be cleaned, it is inside the cylinder. You'll get dirty in the city in about a month and a half if you have windows open or air out of windows. I will use them over the summer and then try to sell the car or throw it away and replace it. Three months later you could buy another one! Not to mention it keeps turning itself off - maybe it's a handy feature [Edited 8/19/19: Levoit contacted me and sent me a replacement block and filters and asked me to return the old block. It should NOT turn off.] Unless it's set on a timer, it should stay on. Two filters in 3-4 months! Filters are now $80 each; significantly higher than the previous value. Too expensive.
