Watch out for
- Unit is large and heavy at 21 pounds, potentially less portable

The Heapets P339 is a pet-focused air purifier designed to tackle floating hair and dander across a substantial 4200 square foot area. Built for open floor plans and homes with multiple pets, this unit prioritizes high-capacity filtration over compact design. Bottom line: if you need a large-room purifier specifically for pet allergens and are willing to trade portability for coverage, the Heapets P339 is worth considering, but the absence of independent performance data means you are buying on promise rather than proof.

Design and Build
The Heapets P339 is a physically large unit, measuring nearly 24 inches tall and 15 inches wide, with a depth of about 9 inches. At 21 pounds, it is not designed for frequent relocation; you will want to place it in a central location and leave it there. The build appears robust, with a footprint that suggests a high-capacity filter stack. The exterior finish and control panel details are not specified in the available data, but the overall design prioritizes function over aesthetics. Given its size, it is best suited for floor placement in a living room, great room, or open basement area.
Performance and Features
Filtration System
The Heapets P339 uses a HEPA filter to capture airborne particles. While the specific grade (e.g., H13 or H14) is not listed by the manufacturer, HEPA technology is generally effective at trapping 99.97% of particles as small as 0.3 microns, including pet dander, dust, and pollen. The product description emphasizes its ability to suck up floating pet hair, suggesting a pre-filter or high airflow design to handle larger debris before it reaches the main filter. No additional filtration stages like activated carbon or ionizers are mentioned in the data.
Coverage and Airflow
The purifier claims a coverage area of 4200 square feet. This is an extremely high number, typically associated with commercial-grade units. For residential use, such a rating likely assumes ideal conditions (e.g., open floor plan, high ceilings, and multiple air changes per hour). Without a CADR (Clean Air Delivery Rate) value, it is impossible to verify real-world performance. The unit’s large physical size and weight support the idea of a powerful fan and substantial filter media, but buyers should temper expectations until independent testing is available.
Controls and Smart Features
No information about control types (physical buttons, remote, app) or smart features (Wi-Fi, sensors, auto mode) is provided in the data. The absence of such details suggests the P339 may offer basic manual controls, typical of many large-capacity purifiers. Potential buyers should check the product listing for specific control panel images or descriptions before purchase.
Maintenance and Running Costs
Maintenance details for the Heapets P339 are not disclosed by the manufacturer. As a HEPA-based unit, it will require periodic filter replacements, but the frequency and cost of replacement filters are unknown. The large filter size likely means replacement cartridges will be more expensive than those for smaller purifiers. Owners should plan for regular pre-filter cleaning (if present) to prolong the main HEPA filter’s life. Without official guidance, a reasonable assumption is a filter change every 6 to 12 months, depending on usage and air quality.
What Owners Say
At the time of this review, no buyer reviews or user feedback excerpts are available for the Heapets P339. The product was first available in November 2024 and has a listed rating of 4.3 out of 5 stars, but with zero reviews, this rating appears to be a placeholder or system default. Prospective buyers should monitor the Amazon listing for genuine owner experiences before making a decision.
Pros and Cons
Pros
- Claims coverage of 4200 sq ft, suitable for large homes and open floor plans
- Specifically designed to capture pet hair and dander
- Uses HEPA filtration for fine particle removal
- Large physical size suggests high-capacity filter and fan
- Relatively new model with potential for modern features

Who Should Buy It (and Who Should Skip It)
The Heapets P339 is a good fit for homeowners with large living spaces (3000+ sq ft) who own pets and need a dedicated unit to manage floating hair and dander. If you have an open floor plan and can accommodate a bulky, stationary appliance, this purifier offers the promise of high coverage at a competitive price point. It may also appeal to those who prefer a simple, no-frills HEPA unit without smart connectivity.
Skip the Heapets P339 if you need a compact or portable purifier, or if you require verified performance metrics like CADR or noise levels. Budget-conscious buyers should also consider that replacement filter costs are unknown. Those who rely on user reviews and independent testing to guide purchases may want to wait until more feedback accumulates. For similar options, check out our reviews of the Cleanforceair H13-Grade or the KNKA APH4000, both of which offer high-capacity HEPA filtration for large rooms.
Final Verdict
The Heapets P339 enters a crowded market of large-room pet air purifiers with a bold coverage claim and a focus on hair capture. Its HEPA filter and substantial size suggest it can move significant air, but the complete lack of independent performance data and user reviews makes it a gamble. If you are willing to be an early adopter and have a space that matches its dimensions, the P339 could deliver on its promise, but proceed with caution.
For now, the Heapets P339 remains an unproven option. We recommend comparing it with established models that have transparent specifications and verified owner feedback. If you decide to purchase, keep your expectations realistic and monitor the filter condition closely. The Heapets P339 has potential, but it needs to earn its reputation through real-world use.
FAQs
What is the coverage area of the Heapets P339?
The manufacturer states a coverage area of 4200 square feet. This is likely based on ideal conditions such as open floor plans and multiple air changes per hour. Without a CADR rating, real-world coverage may be lower, especially in rooms with obstructions or closed doors.
What type of filter does the Heapets P339 use?
It uses a HEPA filter for particle capture. The specific HEPA grade (e.g., H13 or H14) is not listed. HEPA filters are effective at trapping pet dander, dust, and pollen. The unit may also include a pre-filter for larger debris like pet hair, but this is not confirmed.
Is the Heapets P339 heavy or difficult to move?
Yes, the unit weighs 21 pounds and has dimensions of approximately 24 x 15 x 9 inches. It is not designed for frequent relocation. You should place it in a permanent spot and avoid moving it between rooms.
Does the Heapets P339 effectively remove pet hair from the air?
The product is marketed specifically to suck up floating pet hair. While HEPA filters can capture hair that is airborne, most pet hair is larger and may be trapped by a pre-filter. Without independent testing or user reviews, the actual effectiveness for pet hair removal is unverified. Consider it a promising feature rather than a guaranteed result.
