[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

Product Link: https://www.costco.ca/fellowes-aeramax- ... 38266.html

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

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.
