Review on VEVA Premium 2 HEPA Filters and 6 Pack of Pre-Filters - Compatible with Air Purifier Models AC4100/AC4150BLCA and Replacement FLT4100 Filter E by Joseph Scalea

We have a 4100 hepa filtration machine. In short we live in San Francisco downwind of the terrible wildfires but our house is too small for bigger ones models capacity. Thus, the small block runs almost constantly at medium and high speeds. We tried this brand of Veva filters for just under two weeks. It seems to work just as well as the OEM filters and the idea of having three carbon pre-filters for each HEPA filter is intriguing. Of course, all that solid wood ash needs to be contained, and there's a lot of that in the air, both inside and out. They say that normal filters work normally for 6 months, with such bad air we had enough for a maximum of 2 months of use. So the Veva brand should give us a significant cost reduction.
