We have noticed a significant decrease in our allergies and in the dust in our home.
Replacing the prefilters every 3 months is a breeze - you just unscrew the bottom, unwrap the old one and wrap the new one onto the HEPA filter. (We do it outside to reduce dust in our home).
The one issue I have with it is the noise. If you came for something quiet you might want to look elsewhere. The consistent sound of what I can only relate to a central vacuum system constantly running forced me to shut it down for the night, even on its lowest setting. I imagine that it's a sound I could get used to but for now I just run it during the day on low when I'm home and medium when I'm away. The high setting almost seems like overkill to the point where the air being thrown out I would image presses it down to the ground. Blow through a straw as hard as possible and you get the tone of what this thing sounds like, but louder. Another small problem would be the brightness of the fan speed light, it's quite bright in a dark room.
Back to the high note though. The bottom is held off the ground by 4 half inch thick soft rubber pads so the little vibration it does produce is dampened to the point where the room below me can't hear it running. The entire top of the unit comes off by turning a very large knob on the bottom at which point the entire top/grill assembly comes off and reveals the filters simply sitting on the base (Though I must add that the filter makes a perfect seal against both ends and the unit assembled pushes everything to where it should be) so maintenance is quite simple and based on how large that filter is, it doesn't have to be replaced often. To top it off, the room SMELLS different. The AIR in here is clean, and with many cats, that's new.
Overall, it's a keeper, just louder than I was lead to believe.
I subtracted 1 star for two issues that need to be addressed by the company.
1) removal of the ridiculous blue LED light - it will kill your sleep patterns until you disassemble the machine and remove it from the circuit board
2) the lack of sanitation by way of a UV-C bulb. It's possible in the engineering phase to add a UV-C bulb that would not produce ozone. This product only mechanically filters - which is nice. But it would be nicer if it included a couple technologies from the last 10+ years.
This device would be a home run if it had a UV-C bulb operating above 240nm (preferably 253.7nm) to purify (kill germs) the air in addition to cleaning it (removing particles), all without creating ozone. Sadly Honeywell was a bit cheap here. A ridiculous benefit would be an ozone generator on a 4 to 10-minute timer per 24 hour period to keep the ppm down.
Definitely looking at mid 40dB to 60dB which is a little louder than smaller room models. Wouldn't trade this one for the world though. I also have owned the Honeywell 17000s since 2008 which is probably 5-10dB quieter, but maybe only does 1/3 to 1/2 as much air. The Honeywell 17000s I can tolerate on loud in the next room over or medium in the room I occupy. This 50250 I have to run on low or medium. High is just too loud unless vacuuming/etc.
This 50250 filters way way way way more air than the 17000s though. It's not even close. I used the 17000s in college for a dorm room and it was great. But for a 1300sq. ft apartment with 2 bedrooms the 17000s cannot do the living room very well. This 50250 combined with the 17000s in the living room bring me back to feeling how the 17000s felt in a bedroom. I'll eventually get 2x 50250's in the living room and put the 17000s in the bedroom to hold me over until I replace the HVAC and add the parts that any decent home should've had during the building process.
I still think the blue lights on the machine are BS and I will probably disassemble at some point and remove them from the circuit board. Things need to stop coming with lights and beepers.
Additionally, I kind of wish CFM was readily listed. CADR & sq. ft are both the wrong units to measure volume and air changes (which you want 2 to 9 per hour) depending on what you're doing or how bad your asthma is. I guess companies use these measurments to seem more "relatable" to consumers, but it really just feels like a cover up.
The best answers on every air filter would be:
CFM, dB, filter % by micron size, filter cost, replacement interval, yearly watt usage
---> all listed by in a chart by speed setting (low, med, high).
Companies just don't want you to know if they're really the best or not. Such a shame it's left up to red boxes, bold text, and random marketing/lobbying.
*note* I did have to disassemble the 17000s after 2-3 years of running it because the motor was making bearing noise. I greased it with Pennzoil and it ran fine for 5 years then I did it again with some Amsoil nlgi #2 and haven't' had any issues since.
