4.0 out of 5 stars Seem to help. Update on my update

Style: MSA3S Air PurifierVerified Purchase
Update 2: I found less expensive replacement filter cartridges that work without modification. It seems the cartridges might work on a timer basis with replacement about every 3 or 4 months as indicated by the unit lights. The replacement filter was down to 1/4 as per light indicator. I pushed the reset button for about 5 seconds and the light indicator is now reading like it was new. I will monitor the operation thru dust accumulation on furniture. If I lived in a very active home, I could understand the fast depletion of the cartridge. That is not the case. I am wondering if most manufacturers of household units and their cartridges also work on the timer basis per operational hours and not actual air quality? I guess this is a question for manufacturers of both the unit and cartridges. I saved the original filter and wonder if the same will happen
UPDATE: My house is not high traffic and I only have 1 small dog that does not shed. I do the regular, not over the top vacuuming of the floor and furniture. I have not done any frying or heavy cooking. The filter is only 2 months old and is down to one quarter of life left. Knowing that an air filter is just a fan and filter, my next purchase will be a less expensive brand with cheaper and maybe universal type filter. I have noticed less dust on the furniture and electronics (dust magnets!) but think smaller units, with strategic placement might do the job as well. I still compliment the manufacturer for making a good product, but filter cartridge life is no where near what is advertised.
I purchased the smart model, my dumb move as it was impossible to pair with my Android phone even after Customer service and I tried every workaround. I was refunded the difference in price. The customer service was honest in telling me there was no difference in the units. I have been running it on Auto since my purchase about a month ago. I hesitated reviewing until I saw if it made a difference in dust and if it actually covered the square footage as advertised. It has made a difference in dust and helps eliminate cooking odors that linger. It is very quiet even on high fan. The indicator seems to be accurate turning from green to yellow to red as air quality diminishes and changes back to green. You can notice the difference in the air smells. Since the coverage area in less than stated, I will be purchasing another to put in the larger master bedroom. Bottom line, don't look for miracles. Make sure you dust and vacuum before your initial startup. Unfortunately it won't suck the dust off or out of furniture; you have to do that yourself. Since I'm purchasing another, that's testimony enough to the fact that this air purifier does help. The filter cartridges are not expensive and seem to last. Remember, as in all air purifiers, they are just fans and filters.

A dedicated air purifier is better for every day use. Besides the fact that it isn't unsightly like having 4 filters taped to a box fan, air purifiers also have ionizers and charcoal filters for removing bad smells. They also often have automatically adjusting fan speed based on air quality.
So yeah, the DIY "cube of furnace filters" work well, but they are mainly used in situations where you are experiencing extreme air pollution and you wouldn't mind running the ugly massive duct taped monstrosity because you need to clean a LOT of heavily polluted air.

Decision time, I may have to return this and stick with the Winix c545 that's coming tomorrow.

The CADR of this unit is 112. So you need SEVEN of these to equal one CR box.
Seven of these will be insanely loud, and more unsightly than one CR box. (You can buy aesthetic CR boxes. Don't buy low quality stuff like this when it performs so much worse.)

One CR box with a good quality fan is actually quieter than a single air purifier - most of which have cheap loud small fans.

HEPA units are almost all functionally scams. Dust is generated or blows in faster than the filter can clean the air. (Home air exchanges with outside air something like 2x an hour. If your filter doesn't have the CADR to keep up, it's kinda useless.)
Not to mention they deliberately did not get it on Energy Star or AHAM listed/certified list because they know they are inferior to popular models from Winix, Coway, or even Shark. 1700~2000 hour filter life seems suspiciously short for a filter this size so either they assume people will run it at higher speed or they just want to milk more filter sales. Given the unit size and weight very close to the Winix, it really should perform much better if it has the right components (mainly a DC brushless motor). This Seattle company seems to specialize in water filtration so maybe they got this crappy model cheap on Alibaba to jump on the air purification bandwagon.
Get biggest filter possible, run at lowest setting to achieve desired air change rate.

Did you install the shroud? It makes them considerably quieter.
