[Home Depot] Winix P300 Air Purifier $148 ($100 off, regular of $248) *Edit: Now $137*

The're sold out online, but I was able to order one for pickup. Check https://stocktrack.ca/?s=hd&sku=1001103940 for any in store near you.

This is the same brand that sells the 5500-2 and 5300-2 air purifiers.

This unit isn't quite as powerful as those two, but still very good, and designed for rooms a bit smaller. A comparable unit in performance to the P300 would be the Honeywell HPA200. The difference would be the P300 is quieter, consumes less power, and costs less to replace filters. HEPA changed annually and carbon every 3 months, which you buy as a set for ~$34 (Generic Brand: https://www.amazon.ca/Carbon-Replacemen ... 807&sr=8-3).

CADR Rating: Dust 197, Pollen 197, Smoke 214
CADR Average: 200
AHAM Rating: 300 sq. ft. / 5 air changes per hour on Max
Consumption: 4 - 60 watts
Db: 26 - 55 db(A)
CFM: Speed 1-4 : 40, 90, 140, 195

if 195 is the max cfm it can't have a CADR above that

How is this with pet odor? We have the Levoit LV-PUR131 currently but find it doesn't do anything to absorb or eliminate waste from our cats' litter box.

CADR Rating on HD(.com) state 197, close to Winix rating. Looks like HD(.ca) halved all of the CADR numbers, which isn't close to the max CFM. Maybe they were measuring it based on a lower fan setting? Or auto perhaps?

*Edit* HD(.ca) listed the CADR rating for the P150, not the P300.

Wish we could get Winix 5500-2.

This guy explains what you should be looking for in an air purifier.

I'm not too sure what to look for, when comparing Air Purifiers

You'd want it to use replaceable HEPA filters, not permanent filters, or HEPA "like" filters. Carbon filters as well for odours. The higher the CADR the better, as it can process and clean air faster at a given room size. Cost of and frequency of filter replacement, and how much it costs to run. Avoid ionizing ones as they emit ozone which is dangerous for your health.

It's better to overestimate the sq. ft. than to be even or lower. Buying a higher output purifier and running it on a lower/quieter setting is better and usually cheaper than buying one rated just for your room size and having to run it full speed all the time.

The one you listed is a pretty weak unit. https://www.fellowes.com/us/en/products ... US-9320601

Any recommendations on something with UV? Not sure if it's a scam or not. Wonder if my boss will buy one at our small office to circulate air and kill any viruses??

Thanks OP for the sale highlight! I've recently been researching air purifiers. Main goal is to reduce dust, i'm not that allergic. Was thinking about this deal but someone suggested larger unit and so I figured I should not go for this one? Winix seems like decent brand on quick googling but wirecutter suggests operating costs higher and that is a big aspect I would like to keep down.

Wirecutter is usually a reasonable start point for decent options if one is not expert on subject
https://thewirecutter.com/reviews/best-air-purifier/

They like the Coway AP-1512HH Mighty which is $389 at amazon.

Does anyone have thoughts on this unit and is there any price records on sales? What to look for to be a good price? I tried the site and forum search for "coway" on RFD but came up empty.

THanks

Don't focus too much on the specs folks. If you're like me, you'll just leave it on auto anyways.

I clean the mesh filter every two weeks, and replace the filter annually. Just buy a unit with reasonably priced filters and call it a day.

My Winix on auto filters out a considerable amount of dust.

Coway and Winix are basically the two major South Korean brands. The Coway Mighty is a stronger unit. I also considered it, but the price is quite high and it usually doesn't go on sale that often. And at the moment, it's more than double the price of the P300.

Mighty: 326sq. ft. CADR Pollen: 240, Dust 246, Smoke 233. (Wattage: 4.9 - 77.8) $389
P300: 300sq. ft. CADR Pollen: 197, Dust 197, Smoke 214. (Wattage: 4 - 60) $148

If you have either of them in a room that is in the 200 - 250 sq. ft. range, you would probably only need to keep them both on lower fan speed. So electrical costs would be comparable. For replacement filters I haven't looked into the mighty, but given current prices (without tax), you could buy filters for the next 7 years for the P300 before you even reach the price of just the Coway unit. The affordable price of replacement filters, is one of reasons I also went with the P300.

This changes of course once your room size starts to get bigger and closer to the max of the P300. The Coway will be able to perform at lower speeds longer, while the P300 will have to increase earlier to perform comparably.

Here is another video I fell upon when researching air purifiers.



Since then, he made his own company but shipping to NA is very costly.

You can probably make it yourself and if you are handy, make an enclosure so you don't look so cheap.

This method was also briefly discussed in the wirecutter review and they kind of dissed it but I guess they didn't bother watching the entire video because their quote was wrong -- he did measure the effectiveness of his homemade model by running it all day in his room and not just measuring in front of the filter.

What I learned from the reviews are the larger units are better than the smaller one, as they pump more air through the HEPA filters. The small units (which I did buy one for my daughter's room) are helpful if you live in a closet.

This one has plasmaeave to kill gems and virus. It is a knockoff version of Sharp air purifier. If it functions as good as the Sharp models, it is an excellent buy at this price.

From what I've read, UV is ineffective in portable home air purifiers. Must be exposed for several seconds (30?) to be effective which is why it's better for static objects. UV device inside air purifiers is too small too.
