Sans HEPA 13 Air Purifier - 780ft² ultra-quiet home air purifier with pre-filter, activated carbon, and UV-C light

Q: so it's safe to run this air purifier on Auto 24/7? There's no fire hazard?

It is absolutely safe to run Sans 24/7 and not a fire hazard. We recommend running the unit 24/7 and Sans is also UL certified.

Q: Anyone else have a weird, strong "Earth, dirt-like" stench within 2 days of using this? And yes, I did remove the plastic from the filter ”

We did not. It runs great and has made a huge difference in our house. We really like it.

Q: how is this different from this https://www.amazon.com/Afloia-Purifier-Cleaner-Deodorizer-Allergies/dp/B088R4JWW3?ref_=ast_sto_dp?

Imitation is the sincerest form of flattery! Sans is the real deal with SmartPure Technology (watch Sans work with our real-time AQI screen and Auto Mode that adjusts filtration based on precise laser sensor readings), a full 1lb of Activated Carbon in the filter (more than other brands), the longest warranty of any air purifier (5 years!) and of course we're based in the USA.

Q: How often should uv light need replaced?

wow, we have had our machine for almost a year. we have not had to replace the light yet. we dont use it 24/7 either. we use the machine at night when we sleep and turn it off when we wake up. i do replace the filter as recommended. i also blow out the machine itself when i replace the filter. i know you are talking about the uv light but we have never replaced it, sorry, know that is not the answer you are looking for.
