burtran a31 nano oxy hepa 14 air purifier review hospital grade filtra...
All in all, this is a great air purifier. The multiple layers of air filtering are a very nice feature and I really like the HEPA 14 quality. The touted benefits of the negative oxygen ions seems a bit overblown and overhyped, but there doesn’t seem to be a down side to it. It’s quiet and I really appreciate having the additional protection, especially during this time of year with wildfires and the upcoming flu and cold season. The price is pretty high for an air purifier, though, and if you go with the name brand replacement air filters you’re paying a pretty high price on an annual basis. Overall, I think it’s a great air purifier and designed well.
Pros
- Incredibly quiet air purifier. You’ll forget it’s there
- Layered air filtration to extend the duration of the HEPA filter
- Well built and designed
- Directional air output can be adjusted to optimize to the room
Cons
- The app functionality is pretty basic. Would be nice to see some better stats over time and a schedule function
- Price is pretty steep
