Yes, if you live where Philips sells it: about 353 CFM of clean air and as quiet as 15 dB, by Philips' numbers. In the US, buy the Levoit Core 600S-P instead: AHAM certifies it at 391 CFM, and Amazon.com sells it.
Philips PureProtect Pro 4200 review
The short answer
It is a strong purifier where it is sold. Philips rates the PureProtect Pro 4200 (model AC4220) at 600 m³/h of clean air, about 353 CFM, and as quiet as 15 dB. It ships with two HEPA filters that Philips says last up to a year. Philips sells it in Europe, the Middle East and Australia, and the only matches on Amazon in the US on November 4, 2026 were off-brand filters. For a US home, the Levoit Core 600S-P cleans more air (391 CFM smoke CADR, AHAM-certified for 606 sq ft), is ENERGY STAR, and Amazon.com sold it for $269.99 on November 4, 2026.

At a glance
Who it's for
A large living room in a country where Philips sells it. Philips says it covers up to 156 m² (1,679 sq ft).
The standout number
600 m³/h of clean air (about 353 CFM) and as quiet as 15 dB, by Philips' figures.
The catch
Philips' 1,679 sq ft cleans the air only about 1.6 times an hour. At the 4.8 times an hour AHAM uses, 353 CFM fits about 552 sq ft. No US lab directory lists it.
The PureProtect Pro 4200 vs the Levoit Core 600S-P and Blueair 211i Max
The Philips CADR is Philips' one particle figure (600 m³/h, which we convert to CFM), not an AHAM smoke test, so read it as a rough match. The Levoit and Blueair rows are AHAM-certified smoke CADR. Quietest setting is the maker's figure. Filter cost is the genuine filter on Amazon (Levoit every 12 months, Blueair every 9). Power cost is running all day on high at 18.83¢ per kWh. Philips publishes no wattage, and the 4200 has no Amazon US price, so its cost cells are blank. Amazon prices on November 4, 2026.

Frequently asked questions
Is the Philips PureProtect Pro 4200 worth it?
Where Philips sells it, yes: about 353 CFM of clean air, as quiet as 15 dB, with two filters Philips says last up to a year. In the US, the Levoit Core 600S-P is the better buy: AHAM-certified at 391 CFM and $269.99 at Amazon.com on November 4, 2026.
Philips PureProtect Pro 4200 vs Levoit Core 600S: which is better?
The Levoit cleans more air: 391 CFM smoke CADR (AHAM-certified) vs about 353 CFM (Philips' own figure). The Philips is quieter on low (15 vs 26 dB). In the US the Levoit is the one you can buy on Amazon and the one with a certified rating.
Can I buy the Philips PureProtect Pro 4200 in the US?
Philips lists it on its sites for Australia, the UAE, Bahrain, Oman, Jordan and Pakistan, and European stores carry it. We searched Amazon US on November 4, 2026 and every match was an off-brand FY4200 filter from a third-party seller. Philips' model number there is AC4220/12.
What is the CADR of the Philips PureProtect Pro 4200 in CFM?
Philips rates it at 600 m³/h. That is about 353 CFM (600 ÷ 1.699). Philips gives one particle figure, not separate smoke, dust and pollen numbers, and the model is not in AHAM's directory.
What size room does the Philips PureProtect Pro 4200 cover?
Philips says up to 156 m² (1,679 sq ft). With an 8 ft ceiling that cleans the air about 1.6 times an hour. For allergies or smoke, size it like AHAM does, at 4.8 times an hour: about 552 sq ft (our math).
How long does the Philips PureProtect Pro 4200 filter last?
Philips' filter page for the FY4200/30 set says "Lifespan up to 1 year" and "In the box: 2 filters". You change both at once: one goes in the bottom of the purifier and one in the top. Philips says the life depends on air quality and use.
How do you reset the filter on the Philips PureProtect Pro 4200?
Put both new filters in, then hold the filter reset button for 3 seconds. Philips' manual says: "Press and hold the button for 3 seconds to reset the filter lifetime counter." The manual marks that button with an icon, not a word.
How loud is the Philips PureProtect Pro 4200?
Philips says it is "as quiet as 15 dB(A)" on its lowest setting and quieter than normal conversation at top speed. Philips gives no top-speed figure.
Sources. CADR, room size, noise and filter life are Philips' own figures from its AC4220/12 and FY4200/30 pages, read November 4, 2026. The model is not in AHAM's directory or on ENERGY STAR's list, so no third party certifies these numbers. The CFM, square-foot and air-change figures are converted by Verified HVAC Data from Philips' metric figures. We publish no star ratings and take no payment for placement.
