@iwilsker I just answered my own question. It is not recommended to clean the charcoal filters, but to replace them every 3 months (unit comes wit 4 carbon filters good for a year). The HEPA filter cannot be cleaned but must be replaced annually.
Sets of 4 carbon and 1 HEPA filter are on Amazon for about $65. HEPA filters alone are about $35.
It may be more cost effective to purchase multiple units from MEH (that include all 5 filters) than to buy replacement filters alone on Amazon.
UPDATE: Third party charcoal and HEPA filter bundles containing 4 to 6 charcoal filters and a HEPA filter are available on Amazon for between $30 and $40, and an EOM filter set is available for about $43. Look at the “Customers who viewed this item also viewed” section on the Amazon page.
I bought one of these a few years ago, and they’re indeed pretty “great.” The reason for this, in my opinion, is the design of the unit: it draws air from the front, and ejects it from the top, at an angle. This means that you can put it relatively close to a wall, while still getting good efficiency. Many other purifiers draw air from the back (or even from all around, like those cylindrical Honeywell units; good for a centerpiece, but not so great is you want to place it in a corner.
Now I will teach you guys a trick (that you can find in many Amazon reviews anyway): prolong the life of your filters by buying cheap air conditioning carbon filters, cutting them to size, and putting them over the carbon pre-filter (they fit just fine, and in fact will make the seal around the edges of the filters even more leak-proof). This will buy your expensive pre-filters a lot of extra lifetime. Just keep in mind that the whole odor/smoke elimination works as an effect of the activated carbon/charcoal doing its magic, and that stuff does get used up over time. The filtration system is essentially just a fan drawing air through a mesh, and that in itself isn’t enough to trap tiny particles.
The PlasmaWave thing is more or less just a gimmick, and produces a noise that can get annoying if it’s otherwise quiet enough to draw attention to it. It’s almost like a dog whistle, but for humans. I tend to turn it off.
@warpedrotors I wish our former next door neighbor had had that courtesy. (Former because we moved, not because he’s dead or anything.) He was a pot dealer (and had a small grow op in his apt.) and it stank through the walls like we were living next door to a dead skunk.
In for one. I have a…few…animals. I have one medium Honeywell air purifier near one batch of litter boxes, but I’ve been putting off getting more because they tend to be pricey as hell. Let’s see how this one does.
@communist Incorrect! You want to have this URL open at 3:58: Linky
Then refresh at exactly 4:00 and purchase once the item info pops up as available!
mediocrebot gets overwhelmed on high demand items, so safer to do it manually when it counts.
No way, man, I’ll pass. I only look for the six-stage filter systems. The extra two stages filter out the smell of ennui and despair. Which, if you’ve seen my in-laws, are hard things to get out, especially if they’ve spent a week with you.
Got mine and I like it (for the most part) but I feel like it is lying to me about the current air quality. When you first turn it on, it does an air quality check, and then tells me that my air quality is in the orange range. After running it for a while, it seems to think everything is better and it goes to green. But if you turn it off (and unplug it) and then turn it on again, we are back to the orange range for a while.
@cainunable Got mine yesterday, and it did the orange light thing too, just like yours. Mine goes orange again though, after about 15 minutes or so. And the buttons on the front don’t work - only the remote can turn it on, adjust fan speed, etc. And I only got one carbon filter, not 4x. Neither one of those is a killer, but together, it’s kind of annoying, because as far as I can tell, the machine is doing it’s job - the air in the living room does smell and feel cleaner, like a nice hotel room lol. Gonna be calling that warranty number to see what all is involved with unit repair/replacement.
@cainunable Right! it just seems to cycle into orange light territory every 15-20 minutes or so, regardless of what is going on in the room. Might need to put it into a closed, small room over the weekend and spy on it to see if the light still goes orange at the same frequency. Or, maybe I’m learning I live in an air quality nightmare? At any rate, I fixed the button issue I was having by taking off the front, and putting it back on again.
Did everyone get just 1 carbon filter? Or just some of us?
@speaker184 I have had mine in my office with me for the last couple of days and it really only seems to cycle to orange once or twice during that 8-10 hours.
Like you, I also only got 1 carbon filter.
I am beginning to think that the air quality monitor does work at least to a small degree though. If someone in the family farts in the same room as it, usually within a few minutes it will kick into high gear. I’m sure my son is more than willing to fully test that hypothesis.
Same as @speaker184, I got one carbon filter (which is also the prefilter?) and not 4. Haven’t tried the remote because Meh hasn’t sold batteries recently I was too lazy to go get the batteries yet.
The difference between each fan speed is very noticeable, from basically silent to HOLY SHIT TORNADO in just a few button presses. Even the difference from 1 to 2 is substantial. I do feel like this thing will clean some air. This purchase is a win. I kind of wish I’d bought more than one.
So how many filters were we supposed to get? I’ve been out of town for 2 weeks and just opened mine. The description now says 1x pre, carbon and hepa filter, but I don’t remember if that was the original text. Regardless, I got a thick white hepa filter and thin foam like black (carbon?) filter. Did anyone get more that?
Also the “Front” arrow and label on the hepa filter points to the back of the unit. If I put it in according to the arrow, then the pull tabs and carbon filter end up on the inside.
One year (give or take) later and it’s still running well. When I first got it, only 1 replacement charcoal filter was in the box(accompanying literature said there were 2), so I contacted the company. A few days later, I had received 10 charcoal filters in the mail. Decent customer service is rare these days and much appreciated.
