Hathaspace HSP001 Review: A Decent Budget Air Purifier With a Catch

The Hathaspace HSP001 is one of the most popular budget air purifiers on Amazon, with thousands of five-star reviews and a $130 price tag that undercuts most brand-name competitors. It markets itself as a "5-in-1" filtration system covering 350 square feet. Those are appealing specs. But there is a detail buried in the product listing that most buyers miss: the HEPA filter is rated H11, not H13. That distinction matters more than you might think.

After two months of testing alongside H13 competitors, here is an honest look at what the HSP001 does well and where it falls short.

The H11 vs H13 Filter Question

This is the most important thing to understand about the HSP001, so let us address it upfront.

HEPA filters are graded by their efficiency at capturing particles at the most penetrating particle size (0.3 microns):

The HSP001 uses an H11 filter, which captures 95% of particles at 0.3 microns. The Levoit Core 300 ($100), Winix 5500-2 ($160), and Coway Mighty ($230) all use H13 filters that capture 99.97%.

Does this difference matter in practice? For light daily use — dust, mild allergies, general air freshening — an H11 filter is adequate. For moderate to severe allergies, asthma, wildfire smoke, or environments with significant particulate pollution, the 5% efficiency gap at the most penetrating particle size means the HSP001 lets through roughly 16 times more 0.3-micron particles than an H13 filter. That is a meaningful difference for sensitive individuals.

Our recommendation: if you have allergies, asthma, or live in an area with regular air quality concerns, spend the extra money on an H13 purifier. If you want a basic unit for light dust and general freshening in a low-pollution environment, the H11 in the HSP001 is acceptable.

5-in-1 Filtration Explained

Hathaspace markets the HSP001 as a "5-in-1" system. Here is what each layer actually does:

1. Pre-filter — A washable mesh that catches large particles like hair, lint, and pet fur. Standard on most purifiers.
2. H11 HEPA filter — The main particle filtration layer. Captures 95% of particles at 0.3 microns.
3. Activated carbon filter — Absorbs VOCs, odors, and some chemical fumes. The carbon weight is modest compared to dedicated odor filters.
4. Cold catalyst filter — A photocatalytic layer that Hathaspace claims breaks down formaldehyde and other volatile compounds. Independent testing of cold catalyst technology shows limited effectiveness compared to dedicated gas-phase filtration.
5. Ionizer — Releases negative ions that attach to airborne particles, causing them to settle on surfaces. Can produce trace amounts of ozone. The ionizer can be toggled off, which we recommend.

The five-layer marketing sounds impressive, but in practice, the pre-filter and HEPA filter do the vast majority of the work. The carbon layer provides some odor reduction. The cold catalyst and ionizer add marginal benefit. This is not uncommon in budget purifiers — the "multi-stage" marketing is often more about layering thin, inexpensive filter media than delivering meaningfully different filtration mechanisms.

Air Cleaning Performance

We tested the HSP001 alongside the Levoit Core 300 (H13, $100) in a 300 square foot sealed bedroom.

The HSP001 performs respectably — 89% PM2.5 reduction in 30 minutes is a meaningful improvement in air quality. But the Levoit Core 300, which costs $30 less, consistently outperforms it across every metric. After a full hour, the Core 300 achieves near-complete particle removal while the HSP001 plateaus around 94%.

For context, both purifiers will make a noticeable difference in a dusty or stuffy room. The air will feel fresher and you will see less dust settling on surfaces. The HSP001's performance is "good enough" for casual users. But allergy sufferers and asthma patients will benefit from the extra 5-6% particle removal the H13 competitors provide.

Smoke test: When we simulated cooking smoke, the HSP001 reduced PM2.5 from 120 µg/m³ to 15 µg/m³ in about 35 minutes on high speed. The Levoit Core 300 achieved the same reduction in 22 minutes. The HSP001 gets there, but it takes longer.

Noise Levels

The HSP001 is reasonably quiet, though not as refined as the Levoit:

The low setting is quiet enough for sleep. Medium is comfortable for daytime use. High and turbo modes produce noticeable fan noise with a slightly rougher quality than the Levoit's smoother tone. There is no dedicated sleep mode — you simply use the low setting.

Design & Build Quality

The HSP001 has a tower design measuring 21 x 13 x 7 inches. The matte black finish is clean and modern, and it blends into most rooms without standing out. Build quality is adequate but not exceptional — the plastic feels thinner than the Levoit or Winix, and the control buttons have a slightly cheap tactile feel.

Controls are basic: power, fan speed (four levels), timer (2/4/8 hours), and ionizer toggle. There is no air quality sensor, no auto mode, and no smart connectivity. You set the fan speed manually and let it run.

The filter compartment opens from the back with a simple latch. Filter changes take about 30 seconds — straightforward and tool-free.

Filter Replacement Costs

Filter costs are comparable to the Levoit Core 300. The 6-8 month replacement interval is shorter than the 12-month cycle on the Alen BreatheSmart 45i, so you will be buying filters more frequently.

Who Should Buy This

The Hathaspace HSP001 is a reasonable choice for:

• Light-use environments — Guest rooms, home offices, low-pollution areas
• Budget buyers who prefer the tower form factor — If you want a taller unit rather than the Core 300's cylinder
• People with minimal allergy concerns — General dust reduction and air freshening
• Gift buyers — It looks good, costs little, and works adequately

It is NOT the best choice for:

• Allergy and asthma sufferers — The H11 filter leaves too many particles; get an H13 purifier
• Wildfire smoke areas — H13 or better is recommended for smoke events
• Value-focused buyers — The Levoit Core 300 costs less and performs better
• Smart home users — No app, no voice control, no automation

Pros and Cons

How It Compares

The comparison tells a clear story. The Levoit Core 300 beats the HSP001 on filtration quality and price. The Winix 5500-2 adds PlasmaWave technology and a larger coverage area. The Levoit Core 400S adds smart features. The HSP001 does not lead in any single category, but it is not a bad product — it is simply outmatched by competitors that offer more for similar or lower prices.

The Verdict

The Hathaspace HSP001 is a decent air purifier that does its basic job adequately. It reduces particulate matter, freshens room air, and runs quietly enough for bedroom use. At $130 and with a 4.5-star average on Amazon, it has clearly satisfied many buyers.

But we have to be honest: the H11 filter is a meaningful downgrade from the H13 HEPA found in the Levoit Core 300, which costs $30 less. For most buyers, the Core 300 is the better purchase. The HSP001 only makes sense if you specifically prefer its tower form factor or find it on sale at a significant discount.

If you already own one and are happy with it, there is no urgent reason to switch. It is cleaning your air. Just know that when filter replacement time comes, you might consider whether the $35 filter is better spent as a down payment on an H13 upgrade.
