That one seems a bit pricey, I think the best I’ve seen for CADR per dollar is the Conway 400(S) or Medify MA-112.

- nerdbaggy 3y agoYeah they are expensive but the best I have found. The 45i is for like 700 square feet for $400. The nice part about Alen purifiers is the filters last just about a year and lifetime warranty
- bmitc 3y agoWhat type of filter is that? HEPA filters are recommended to be changed every few months.
- nerdbaggy 3y agoYeah they are HEPA and according to the link below it’s good for 12-15 months https://alen.com/products/alen-breathesmart-75i-hepa-filter?variant=40426983292993 https://alen.com/products/alen-breathesmart-75i-hepa-filter?...
- LTL_FTC 3y agoI went down a rabbit hole when California nearly burned down in 2020 and after lots of research came to the conclusion that buying 7x $100 hepa filters is better than buying 1x $700 filter. So an inexpensive Winix ended up being the best for me. One for each room. More air cycles and much less noise when they're scattered throughout the house. This is just for particulate matter. If one cares about volatile organic compounds, VOC's, they need to invest is several pounds heavy charcoal filters. The thin ones that come on most filters don't do anything other than act as a pre-filter to catch the large particles.
- rocqua 3y agoFrom what I know, this holds for air purifiers. Quantity of air moving through matters more than quality of the filter, because of re-circulation. The cool part of a PPS to me is that, because it is a one-shot system (no recirculation) it can actually take advantage of high quality filters.
- LTL_FTC 3y agoYes, sorry. By filters I meant air purifiers with HEPA filters in them. The more cycles, the better.
