Easy to Maintain Replacement Filter
The Pre-Filter A (model HRF-AP1) needs to be replaced every 3 months. A filter light reminds you when to change the filters and they are easy to replace - no tools required.
To ensure stated product performance, use only Certified Honeywell Replacement Filters.
Airborne particles less than or equal to 10 microns in diameter are so small that they can get into the lungs, potentially causing serious health problems.
When inhaled, larger particles (2.5 microns and larger), tend to stay in the upper respiratory tract. Fine particles (2.5 microns or smaller) stay airborne longer than larger, heavier particles which increases the chances of being inhaled. These microscopic particles are considered more harmful because they can move deeper into the respiratory tract.
Air Changes Per Hour
Air circulation depends on many factors, such as room size and configuration. There is no guarantee that all of the air in a room will pass through the filter.
*From the air that passes through the filter. Overall particle reduction depends on many factors including the amount of air processed, the pollutant type and the pollutant introduction rate into the environment.
**When operated with the odor reducing pre-filter. It is recommended that the pre-filter be replaced every 3 months to effectively reduce common household odors and gases in a room. This product does not reduce or absorb carbon monoxide gas. Make sure gas appliances are well ventilated.

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).
-purifies the air in large rooms quickly
-easy to maintain
-prefilter is inexpensive, and you can just vacuum it out
-low power usage
-quiet enough not to disturb while on low
-very noisy on high, but its to be expected its moving large amounts of air
-large, but that's to be expected with such a massive filter
For the video I filmed using my iPhone at 8' away and 3.5' off the ground. I also ran a sound meter to record db during operation. The room baseline was 44db (only central air running).
Noise test comparison (high/med/low setting):
Honeywell 50250-s: 57/52/45
Honeywell 17000: 49/47/45
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.
Oh but I do have one complaint. The blinding blue floodlight-of-an-LED they used. It literally lights up an entire room with a bright blue glow. I used to have to put something over it just to watch TV without the weird blue glow on the ceiling distracting me. Luckily, I'm handy and I found an easy way to fix it and I will show you how.
(See photos) You need a small flathead screwdriver and some black electrical tape. First unplug the unit and let it sit for awhile. While the unit is unplugged, start by prying back the front corners of the silver panel. Pop one side just a little loose, then pop the other side loose. There are tabs on each side, gently pry the edges back until you get the tabs loose and lift, the silver panel lifts off. Inside, the LED is at the end of a clear triangular plastic piece. Right at the end, where the LED is, there is a little clearance, put a small strip of black electrical tape onto the LED, covering it completely. Now pop the panel back in the opposite way it came out, ease the tabs in with the screwdriver if you need to. Now turn on the light and enjoy a soft, muted blue glow that just barely lights the dial.
