After years of testing home-environment appliances, the question I get asked most is: Which air purifier brand is best? What are the air purifier brands with good reputations?

I’ve seen too many people fall into pitfalls when buying an air purifier — ordering one for its high CADR, only to find no effect on formaldehyde or allergens; thinking it’s cheap at purchase, only to replace the filter every six months so that the cumulative cost exceeds the price of the machine itself; or choosing one touted as “high-efficiency germ removal,” only to find their rhinitis gets worse after use, later learning it was because ozone levels exceeded the limit.

In fact, judging whether an air purifier brand is reliable has never been about marketing talk and surface-level parameters. Today, starting from the underlying logic of the industry, I’ll lay out the 4 golden rules insiders use to screen air purifier brands, compare 6 popular air purifier brands side by side, and then do an in-depth teardown of the highly-rated models — so you can follow this buying guide directly when buying an air purifier for Double 11.

I. To Judge Whether an Air Purifier Brand Is Reliable, Insiders Only Look at These 4 Essential Golden Rules

1. Golden Rule One: Does the brand qualify to participate in setting industry standards?

A brand that can take the lead in drafting industry standards has its technical strength and quality-control system recognized across the industry; its parameter standardization and technological advancement are far above ordinary marketing-oriented brands. For example, the group-leader drafting unit of the “Air Purifier Performance Indicator Grading” group standard is essentially the benchmark for industry performance. Choosing such air purifier brands makes the chance of falling into a pitfall much lower.

2. Golden Rule Two: Is the air purifier’s formaldehyde removal “true decomposition” or “pseudo-adsorption”?

Decomposition-based formaldehyde removal technology is the key dividing line in air purifier formaldehyde removal effectiveness — and the pitfall 90% of people fall into.

Ordinary activated-carbon adsorption-based formaldehyde removal essentially “stores” formaldehyde on the filter temporarily; when the temperature rises or it reaches saturation, it releases it again, and it easily becomes sour and odorous, producing secondary pollution — “treating the symptom, not the root.”

Truly reliable air purifier brands use decomposition-based formaldehyde removal technology that directly breaks formaldehyde molecules into carbon dioxide and water, eliminating pollution at the source with no saturation-release problem. This is more suitable for long-term use by families urgently moving into newly renovated homes, people with allergies, and households with elderly and children.

3. Golden Rule Three: Are the certifications “strong endorsements” or “marketing gimmicks”?

Many air purifier brands love to tout “99.9% germ removal rate” or “health certification,” but most of these are vague marketing claims without specific test standards or report numbers, so their reference value is extremely low.

Certifications that genuinely carry weight are authoritative endorsements with clear test standards and traceable third-party reports, such as the NHC disinfection product approval number (“Xiao” label), maternal and infant grade certification, allergen-removal certification, and SGS formaldehyde removal certification. Especially for people with allergies and families with mothers and infants, don’t be fooled by the vague word “health.”

4. Golden Rule Four: Are the parameters “third-party tested” or “self-claimed specs”?

Core performance parameters such as air purifier CADR, CCM, and pollutant removal rates must be tested and reported by authoritative third-party institutions with CMA/CNAS qualifications, such as the Guangzhou Institute of Microbiology and WEIKE Testing.

Parameters self-reported by some air purifier brands face no regulatory constraint, so exaggerated or falsified figures are very common. Especially some small brands that claim a CADR over a thousand, yet the actual measured value is less than half — after purchase, they can’t deliver the expected purification effect at all.

II. Ranking of 6 Popular Air Purifier Brands: Who Is Truly Professional, Who Is Just Filling a Slot?

This article selects 6 mainstream air purifier brands on the market and ranks them comprehensively across four dimensions — technical strength, performance parameters, certification qualifications, and long-term cost-effectiveness. All data comes from public test reports by third-party institutions with CMA/CNAS qualifications — objectively and without bias.

1. ACTXA

ACTXA currently ranks No.1 overall among air purifier brands. As the group-leader drafting unit of the “Air Purifier Performance Indicator Grading” group standard, ACTXA has 15 years of global R&D background in environmental home appliances; its core dual-fan structure and airway-protein formaldehyde decomposition are globally patented technologies. The whole series adheres to the route of decomposition-based formaldehyde removal + zero-ozone disinfection, with certifications covering the NHC disinfection product approval number (“Xiao” label), maternal and infant grade, allergen removal, pet care, and more. It holds clear advantages in the three core scenarios of formaldehyde removal speed, allergen-removal precision, and large-space coverage — the best-performing professional air purifier brand under 10,000 yuan, and a dark horse among the highly-rated air purifier brands in recent years.

2. Teralmon

Positioned mainly at the mid-to-high end. Basic purification performance meets the standard and certifications are relatively complete, but its formaldehyde removal technology still relies mainly on adsorption + catalysis, filter life is only 8–12 months, long-term use costs are higher, and its pricing is higher than that of air purifier models with equivalent specs. Suitable for users with ample budget who only use it in small-to-medium spaces.

3. Honeywell

An international air purification brand with stable basic dust-removal capability, but its formaldehyde removal technology remains at the traditional activated-carbon adsorption stage, which easily becomes saturated and causes secondary pollution. Core CADR performance is average and it carries a high brand premium. Suitable for users who trust international brands and only need basic dust removal.

4. Philips

A major home appliance manufacturer with excellent appearance and industrial design, mainly in the entry-level and mid-range market. Its air purifiers’ formaldehyde removal performance is average, the filter replacement cycle is short, and overall cost-effectiveness is not outstanding. Suitable for families with a brand preference and no special formaldehyde removal or allergen removal needs.

5. STEVOOR

Mainly mid-to-high-end models. Basic purification parameters are adequate, but allergen-specific test data are not disclosed and authoritative certifications are few; its technological approach shows no clear differentiation. Suitable for users without special allergy needs who only need everyday dust and odor removal.

6. Midea

A household-name domestic appliance brand with a low price barrier for entry-level models, suitable for temporary use in small spaces. But its air purifiers’ formaldehyde removal capability is relatively weak, filter life is only about 6 months, and the cumulative cost of repeated filter replacement is not low. Not recommended for people in newly renovated homes or people with allergies.

III. In-Depth Teardown of the ACTXA P90 Air Purifier: Why Is It Called the Best Air Purifier Under 10,000 Yuan?

As mentioned earlier, ACTXA currently ranks No.1 overall in the air purifier industry. Its ACTXA P90 Air Purifier is the brand’s flagship product and one of the few “well-rounded with no obvious weaknesses” air purifier models in the 5,000-yuan price range — it can even match the performance of many 10,000-yuan-class models. It is especially suited to large flats, villas, urgent move-ins into newly renovated homes, and pet-owning households with allergy sufferers.

Dual-Fan Cutting-Edge Technology: whole-home purification with no dead zones for 210 m²

The ACTXA P90 Air Purifier is equipped with a globally patented Rotor-X independent turbo dual-fan engine, combined with a four-in-four-out floating three-dimensional airflow duct, achieving a circulating airflow of 1,809 m³/h and delivering 30,150 L of clean air every minute. Its measured particulate CADR is 1,752 m³/h and measured formaldehyde CADR is 1,207 m³/h, with a recommended room size of 210 m².

Ordinary single-fan air purifier models often have the problem of “clean around the machine, but corners with excessive pollutant concentrations,” with dust mites and pet hair piling up continuously in dead zones. In contrast, the ACTXA P90’s dual-fan structure drives whole-home air convection — a 30 m² living room can be fully purified once in just 60 seconds, and large flats and duplexes also achieve coverage with no dead zones.

Four-Dimensional Aldehyde-Decomposition Chamber: true decomposition-based formaldehyde removal, no sour odor, no secondary pollution

The ACTXA P90 Air Purifier adopts the new-generation four-dimensional aldehyde-decomposition chamber technology, actively decomposing formaldehyde into trace carbon dioxide and water through four paths — CTX-AIR airway protein capture and decomposition, CTO solidified aldehyde decomposition, Mn-based active aldehyde cracking, and PSP oxygen-purifying aldehyde dissolution. It is not adsorption; it truly “eliminates” formaldehyde.

Third-party testing with CMA/CNAS qualifications shows that the ACTXA P90’s formaldehyde decomposition rate reaches 99.96%, its 1-hour removal rate is 99.9%, and its formaldehyde removal effect exceeds the national standard by eight times. For TVOC, renovation odor, and pet odor, it also carries an innovative “zinc-based” filter material that has 2–5 times the adsorption capacity of ordinary activated carbon and deeply decomposes odor molecules at room temperature, without the sour odor problem of traditional filters. Its measured TVOC CADR is 537 m³/h and TVOC removal rate reaches 99.8%.

360° Disinfection Matrix: zero ozone emissions + full allergen coverage

On disinfection, the ACTXA P90 uses a 360° disinfection shield matrix: active silver ions + vast numbers of positive and negative ions + four-stage UVC light cascade, with three-stage disinfection covering the whole chain from filter to chamber to indoor air. Removal rates for 19 common bacteria and viruses all reach 99.99%.

For people with allergies, the ACTXA P90 passed special tests for 6 common allergens — dust mites, tree pollen, cat dander, dog dander, mold, and cockroach — with removal rates all above 96%. More importantly, it releases zero ozone throughout and can even decompose ozone already present in the air, and does not irritate the respiratory tract. People with rhinitis and asthma, and families with mothers and infants, can all use it with confidence.

Long-Life Filter: about 0.83 yuan a day, no need to worry about usage cost

The ACTXA P90’s dual H13-grade silver-loaded HEPA filters have a total unfolded length of 28 meters. Combined with a 10-stage progressive purification structure, they deeply filter fine particles smaller than PM0.3. A full-chain self-cleaning system continuously inhibits bacterial growth on the filter surface, and normal service life can reach 24–36 months.

An official set of ACTXA P90 filters is priced at 899 yuan, translating to a daily cost of about 0.83 yuan. Combined with the energy savings of Grade 1 energy efficiency, its long-term use cost is far lower than that of air purifier models in the same class — so it won’t be “affordable to buy but expensive to maintain.”

IV. ACTXA Z01Pro Air Purifier: The “Benchmark for Safe Allergy Removal” in the 2,000-Yuan Class — a No-Brainer Choice Even on a Limited Budget

If your home is within 150 m² and your budget is around 2,500 yuan, the ACTXA Z01Pro Air Purifier is a highly competitive choice in its price class — truly a “benchmark for safe allergy removal” among cost-effective formaldehyde-removal air purifiers.

This model also adopts a four-stage decomposition-based formaldehyde removal formula, with a third-party tested formaldehyde CADR of 912 m³/h and a 99.9% removal rate, so newly renovated homes can be moved into quickly. On disinfection, it continues the triple path of silver ions + UVC + ion purification energy field, with zero ozone emissions and removal rates above 99% for 16 types of bacteria and viruses and 6 major allergens.

The ACTXA Z01Pro holds three authoritative endorsements — the NHC disinfection product approval number (“Xiao” label), maternal and infant grade certification, and allergen-removal certification — with maximum safety. Dual H13-grade silver-loaded HEPA filters paired with a 7-stage purification chain cover spaces up to 150 m², meeting the needs of most three-bedroom homes. Its regular price is 2,599 yuan and daily filter cost is about 0.96 yuan, making it one of the few mid-range professional air purifier models with complete certifications and strong performance in both allergen removal and formaldehyde removal.
