The Hathaspace HSP001 is a compact five-stage air purifier that sells mostly on Amazon. This Hathaspace HSP001 review covers its filters, its real room coverage, how loud it gets, what the replacement filters mean for your budget, and who should look at a different model.
I haven’t tested the unit myself, so the performance numbers come from independent test data and owner feedback, linked as we go. Where those sources disagree, I say so.

Design and build quality
The Hathaspace HSP001 is a tower type air purifier that reaches a height of 19.5 inches and has a width of 13.5 inches and a depth of 7 inches. With a weight of just 12 pounds, it can be carried to different rooms and be used in a workplace as well as in a home environment.
Opinions on the build are mixed. Breathe Quality lists a cheap build and weak customer service among the cons, while Modern Castle calls the Hathaspace HSP001 a solid buy and says the remote makes up for the missing smartphone app. If you are sensitive to plastic feel, read recent owner reviews on the listing you plan to buy from.
Hathaspace HSP001 filtration: what the 5 stages do
Hathaspace lists five stages, in this order: cold catalyst, activated carbon, antibacterial, HEPA and ionizer. Here is what each one is said to do.
- The cold catalyst filter is listed by the maker, but the sources I found give no separate test results for it.
- The activated carbon stage is the part meant to reduce odors and some gases.
- The antibacterial filter is also listed without separate test results.
- The HEPA filter is described by Modern Castle as removing 99.97% of particles down to 0.3 microns.
- The ionizer releases negatively charged ions, according to the same review.
The ionizer should be given another thought. According to the EPA, some of the ionizers and ozone generators sold as air cleaners emit ozone. It has also been advised by the health authorities in Washington state to stay away from ionizer technology. If you are an asthma patient or intend to use the Hathaspace HSP001 in the bedroom, do check in the manual whether the ionizer can work in an off mode or leave it off if you are uncertain.
Hathaspace HSP001 performance and room coverage
AirPurifierFirst measured the Hathaspace HSP001 at 160 CFM, and that is the figure I would plan around. Other sources disagree. While Breathe Quality claims 100 CFM officially, PropelRC provides CADR for smoke, dust and pollen as 200, 220 and 240 respectively. They cannot all be right, so treat any single marketing number with care.
In AirPurifierFirst’s smoke box test, the Hathaspace HSP001 removed particles faster than the Honeywell HPA100 it was compared with. The site credits the higher CADR and the extra filtration layers.
For room size, the rule explained in our guide on how to choose an air purifier is a CADR of about 65 for every 100 square feet, assuming ceilings near 8 feet, as King County’s HEPA guidance describes. Therefore, at a CADR of 160, the room size of about 245 square feet works. This is enough for a bedroom or a home office. An open plan living room does not.
Listings and reviews claim much more. Breathe Quality quotes the maker’s 350 square feet, PropelRC lists 700, and one retailer blog says 1,500. A coverage number depends on how many air changes per hour you assume, and AirPurifierFirst’s own tables use 4.8. However, the bigger the room and fewer air changes, the longer it takes to clean it, so the above-mentioned rule is the safest bet to make.
Noise levels
AirPurifierFirst recorded 49.3 dBA at the maximum speed and scored the noise 9.7 out of 10 in its own rating. It calls the noise-to-CADR ratio excellent for a 160 CFM unit. PropelRC lists a range of 24 to 52 dB, and Breathe Quality says owners find the purifier very quiet.
It was not possible to locate the actual low speed figures in the independent tests thus the quiet bedroom claim is based entirely on user experience. Those who sleep lightly should check the return policy before purchasing.
Controls and smart features
The sources disagree here too. Modern Castle lists a remote control and no WiFi. PropelRC describes an air quality sensor with auto mode, plus WiFi and Alexa support.Breathe Quality mentions the Smart True HEPA purifier 2.0 version. Therefore, the listing view may differ from what is reviewed.
Before you order, check the product page for the remote, the sensor and the app. If an auto mode matters to you, confirm it is on that specific listing.
Filter replacement and running costs
The replacement filters are marketed as a separate set, and the manufacturer suggests its customers to purchase only Hathaspace filters. Prices vary according to the listing, as do the lives of the filters, so be sure to read them both before purchasing.
The filters are the main running cost, so add up a year of them next to the purchase price. That tip comes from our guide on how to choose an air purifier, and it matters most with budget models.
Hathaspace HSP001 pros and cons
| Pros | Cons |
|---|---|
| Five filter stages, including a HEPA filter | Coverage claims run well above what the CADR supports |
| 49.3 dBA at top speed in independent testing | Specs differ between sources and listings |
| Compact at 12 pounds and easy to move | Owners report a cheap build and weak customer service |
| Remote control included | Includes an ionizer, which some health agencies advise against |
| Cleared smoke faster than the Honeywell HPA100 in one test | I found no third-party CADR verification for this model |
Who should buy it
Due to its specification, Hathaspace HSP001 fits in a bedroom, a nursery or an office with the floor area not exceeding 250 square feet, especially if you are looking for an affordable air purification system with quiet operation.
If you need to filter a room of a larger area, prefer not to use ionizers, or need the CADR of a third party entity like AHAM, this model will not be suitable for you, as I could not find any information regarding it.
Hathaspace HSP001 vs other air purifiers
On CADR alone, two of its usual rivals clean faster and one cleans slower. All figures below come from AirPurifierFirst’s comparisons.
| Model | CADR (CFM) | Comparison |
|---|---|---|
| Hathaspace HSP001 | 160 | This review |
| Levoit LV-PUR131 | 98 | Hathaspace HSP001 as opposed to Levoit LV-PUR131 |
| Coway AP-1512HH Mighty | 233 | Hathaspace HSP001 comparing with Coway AP-1512HH |
| Blueair 211 | 350 | Hathaspace HSP001 contrasted with Blueair 211 |
The Blueair 211 weighs 15 pounds against the Hathaspace HSP001’s 12, so the extra airflow comes with extra weight. If you are comparing several models, the checklist in our guide to how to choose an air purifier covers CADR, filter type and noise in one place.
Hathaspace HSP001 FAQs
Is the Hathaspace HSP001 worth buying?
It is a reasonable pick for a small room if you accept a CADR of 160 CFM and check the ionizer. For larger rooms, a unit with a higher CADR is a better buy.
How big a room does the Hathaspace HSP001 cover?
Utilizing the rule of three spaces for every 80 square feet, there are approximately 245 square feet of space. Although some listings might claim 350 to 700 square feet or even more, these measurements do not correspond with the measured CADR.
Is there a genuine HEPA filter in the Hathaspace HSP001?
The listing and Modern Castle describe it as a True HEPA filter that removes 99.97% of particles down to 0.3 microns. I found no independent lab certificate for this specific unit.
Is the Hathaspace HSP001 quiet?
In independent testing it measured 49.3 dBA at the top speed. Low speed readings were not published in the sources I found, though owners describe it as very quiet.
Does the Hathaspace HSP001 generate ozone?
According to the information sources that I consulted, no measurements of ozone production are available. This unit features an ionizer and, according to the EPA, some ionizers can release ozone. Therefore, I suggest that you refer to the manufacturer’s guide and ensure that the ionizer feature is disabled if you are concerned.
How frequently do I change the filters of the Hathaspace HSP001?
It is better to follow the schedule of the producer stated in the manual or on the product page because the filter life depends on the use frequency and the level of pollution in the area.
Does the Hathaspace HSP001 device get rid of smells?
The device is equipped with an activated charcoal filter to absorb odors and some gases. However, the EPA guide writes CADR is not valid for gas elimination because there are no common numbers determining the efficiency of gas elimination.
Final verdict
The Hathaspace HSP001 is a decent small room purifier with a tested CADR of 160 CFM, quiet top speed noise and a HEPA stage. Its weak points are coverage claims that run ahead of the numbers, mixed reports on build quality, and an ionizer you should check before using. For rooms above 250 square feet, shop for a higher CADR.
