Our verdict on the Hathaspace air purifier
The original Yawnder reviewer liked the purifier's straightforward setup, automatic controls and accessible filter assembly. For the current HSP002, compare its manufacturer-rated particle CADR, replacement filters and the conditions of its five-year limited warranty. Do not assume the older first-person experience establishes the effectiveness of the current model.

Hathaspace HSP002: current model and specifications
Hathaspace’s Smart True HEPA Air Purifier 2.0 is identified as HSP002. The manufacturer describes five-stage filtration, automatic and sleep modes and an H13 HEPA filter. The 1,500-sq-ft marketing coverage refers to about one air change per hour, not rapid cleaning of every room of that size.
| Particle clean air delivery | Manufacturer manual: approximately 450 cubic meters per hour (PM CADR), under stated conditions |
|---|---|
| Manufacturer coverage | Up to about 1,500 sq ft for one air change per hour; more frequent air changes require smaller coverage |
| Filter replacement | Approximately every four months or when the device indicates, depending on actual use |
| Filter care | Do not wash the disposable main HEPA filter or immerse it in water; use only compatible replacement media |
| Noise on high | Manufacturer manual lists up to approximately 66 dBA; not independently remeasured by Yawnder |
| Manufacturer warranty | HSP002 lists a five-year limited warranty, subject to proof of purchase and stated exclusions |

Original Yawnder hands-on review
These are the original reviewer’s impressions of the Hathaspace unit supplied at the time. Assembly, filter layout, packaging and subjective room feel are useful evidence of that sample. They are not controlled pollutant-removal measurements or proof the current HSP002 has every historical feature.
I received the Hathaspace Smart True HEPA Air Purifier for review. I liked its simple controls, filter arrangement and automatic mode. These are my observations of the version I used, not independently measured room-wide pollutant-removal results.
Ordering the Hathaspace Smart True Hepa Air Purifier
Mine arrived from Hathaspace in under a week and was packaged well. Delivery time and buying terms can vary by seller and date.
How Much Does it Cost?
At the time of my original review the price was about $399, with a separate filter-subscription offer. Those figures and the old trial are historical; check the current price, replacement-filter cost and seller’s terms.
Overview of the Hathaspace Air Purifier
Here's a video overview of the device. In the video, you can see how easy it is to change and replace the filter and how loud the device can get on its highest setting which will most likely be rarely used.
Construction of the Hathaspace Air Purifier
My Hathaspace Findings
There's really not much to get this setup. There are instructions but the most important is to remove the plastic wrapping from the filter itself before operating.
This is the second 5 stage air purifier I have tried and I am a convert to this technology. I noticed a difference in the room within minutes after turning this on. That was a subjective impression, not an instrumented air-quality test. Here's a look at each filter.
The black grid is the pre-filter, which captures larger particles. This is a washable filter and to clean it you just need to run it under the sink and use a light scrub brush with a little bit of soap and then let air dry before re-attaching.
The blue filter is the polypropylene prefilter which captures bigger particles so the HEPA filter can run more efficiently. Behind this filter is the HEPA filter which blocks smaller particles. There are tabs at the top that make it easy to remove from the device when it comes time to replace it.
There's also a carbon filter inside that traps odors.
The backside of this is the cold carbon filter. This was the final stage of the filtration process; carbon can reduce some gases and odors, depending on the filter and conditions.
I like that the filters are all put together in one container. When it comes time to replace it, you simply take it out and put back one piece. On the version I tried, I cleaned the pre-filter and wiped down the outer container. Follow the current manual: replace the main filter as directed rather than washing it unless the manufacturer specifically permits it.
My Hathaspace Smart True Hepa Air Purifier Recommendation
At the time, I considered the purifier a good value. I did not measure pollutant removal or compare its noise and cleaning performance in a controlled test. It is very intuitive to operate as it has an automatic mode that will detect air quality and adjust the fan as needed. There's even a night mode that will turn off all the display lights if you keep it in your bedroom. The overall design is sleek and modern so it won't look awkward in your living room.
As we are spending more time indoors it's important that we have an optimal environment for health and productivity. Cleaner indoor air can be valuable, but a purifier alone cannot guarantee better health or prevent illness.

What filtration can and cannot do
A particle filter can capture airborne dust, pollen and other particles passing through it. Activated carbon can reduce some odors and gases, but performance depends on the pollutant and amount of carbon. No purifier removes every pollutant, eliminates every odor or guarantees protection from illness. It does not replace ventilation or remove the carbon dioxide people exhale.
The EPA recommends choosing a particle CADR appropriate to the room. Higher fan settings generally move more air but can be louder. The California Air Resources Board list identifies HSP002 as a mechanical air cleaner; certification does not rate its cleaning effectiveness.
Replacement filters, warranty and buying
Hathaspace’s HSP002 replacement-filter page lists an H13 filter. Its product page discusses scheduled delivery and replacement roughly every four months. Check current stock, price, subscription cancellation and return terms before ordering; your usage and air conditions may affect replacement needs.
Hathaspace currently lists a five-year limited warranty for HSP002 in its model-specific policy. Check registration, proof of purchase, exclusions and authorized sellers before ordering.
How to compare this purifier with others
| Question | What to compare |
|---|---|
| Room size | Particle CADR for the room and ceiling height, at the fan speed you will use |
| Filters | Particle filtration, carbon amount, compatible replacements and total annual cost |
| Bedroom use | Noise and display brightness at your chosen speed |
| Other technologies | Check the exact model’s filtration method and any ozone or ionizer features |
For another design, read our Molekule review. Technology and performance claims are model-specific; we did not perform a controlled head-to-head test for this article.
For bedrooms, compare published smoke/particle CADR at the speed you can tolerate with a correctly sized HEPA unit. Gas and odor performance is separate from particle CADR, and a purifier cannot remove exhaled CO₂ or fix mold-causing moisture.

Frequently asked questions
Does it remove dust and pet dander?
Its particle filter is designed to capture airborne particles that pass through the device. It cannot remove all settled dust or every allergen in a room.
Does it remove carbon dioxide?
No. A particle filter does not remove exhaled CO₂; ventilation is needed for that.
Can I wash the HEPA filter?
Follow the manual for the exact filter. Do not wash a disposable filter unless the manufacturer says it is washable.
Is 1,500 square feet the right size for every home?
The brand’s figure uses one air change per hour. Compare CADR and the cleaning rate you want for your own space; lower fan speeds move less air.
Is the HSP002 certified in California?
CARB lists HSP002 as a certified mechanical air cleaner; CARB certification does not establish how effectively it removes pollutants.

Final verdict
The older Hathaspace purifier made a positive impression for ease of use and accessible filters, while the current HSP002 offers a different published model with a stated filter replacement schedule and warranty. Shop by model-specific CADR, room size, noise and replacement costs. The historical first-person account is not evidence of tested removal of every pollutant or clinical improvement.
