Who the P339 is built for
- Before bringing it home, decide which rooms actually need it. One unit rated for 4,200 sq ft still works room by room, so the pet zone or the bedroom closest to the litter box is usually the place to start.
- Check the footprint where you plan to place it, since a large-room unit needs clearance around the inlet for airflow.
If your living room doubles as a dog run and a cat lounge, you already know that standard purifiers struggle with floating fur. The P339 is aimed at that specific job: a high-suction U-shaped inlet and custom pre-filter cotton are designed to grab hair and dander before they settle, while bio-enzyme activated carbon works on pet smells and household odors. We'd consider this purifier when shedding and odor are the main complaints, not when you want a whole-house unit for a sprawling open plan.
The seven-stage filtration includes an H13 HEPA layer and an anion stage, and the manufacturer says the unit can refresh the air across 4,200 sq ft with a CADR of 205 CFM. We'd consider it for pet zones, open living areas, bedrooms, and basements where fur and odor are the main complaint rather than general dust alone.
Smart features include a PM2.5 display, air quality indicator, pet lock, four fan speeds with an auto mode, timer, and WiFi app control. Sleep mode dims the indicator lights and adjusts automatically overnight, which matters if you or your pets are light-sensitive.
What this price means
At $249.99, this unit is $15.21 below the typical price over the last 90 days of $265.20, which works out to about 6 percent off. That is a modest move rather than a deep one, but it is a real discount against the recent norm.
The current price sits below the typical price over the last 90 days, so it's a reasonable time to buy if you need it now. The rating sits at 4.3 across 514 reviews.

Filters and running costs
The composite filter is found by searching B0HFLVMKV2, and the pre-filter by B0DSZTXBM9. Pet homes clog pre-filters fast, so check how often the pre-filter cotton needs cleaning and whether the composite filter has a stated replacement interval before you buy.
The unit is being transitioned to an updated panel design, and either version may ship during that period. If you care which panel you receive, that is a question to raise with the seller before ordering.
When to skip this one
Skip the P339 if you need a purifier for a single small room and want to spend less. The pet-specific pre-filter and odor stages are the point here, and a basic HEPA unit can handle a bedroom with one cat for less money.
Also pass if you want verified filter prices before committing. The replacement cost is not listed, and pet purifiers live or die on how expensive the consumables are over a year.
