The PuroAir 240 leads PuroAir's lineup with a CADR of 183 CFM (dust) / 181 CFM (smoke) / 204 CFM (pollen) — all AHAM verified, not marketing estimates. At H14 grade, it captures 99.99% of 0.1-micron particles, exceeding the 99.97%/0.3-micron standard True HEPA benchmark. Independent testing by HouseFresh confirmed CADR claims but found real-world effective coverage of ~500 sq ft at 4 ACH, not the advertised 1,000. The 22 dB sleep mode is genuinely quiet — comparable to white noise — and the 52 dB high setting is audible but not disruptive. No smart features means no app distractions, but also no auto mode or scheduling. Annual filter cost ~$40. For allergen sufferers and households wanting medical-adjacent filtration at a consumer price, the 240 is the sweet spot in the entire air purifier market at this price tier.
PuroAir 400 HEPA 14 Air Purifier for Large Rooms
“The PuroAir 400 steps up to handle genuinely large spaces with its higher CADR and same H14 filter standard. It outperforms similarly-priced smart purifiers on raw filtration spec, making it the right”
See Today’s Price →What we like
- HEPA 14 filtration rated for rooms up to 2,000 sq ft
- Higher CADR than the 240 — handles open-plan living areas
- Same H14 filter standard as medical and cleanroom applications
- Handles wildfire smoke, cooking smoke, and fine PM2.5 particles
- CarbonTech activated carbon layer for odors and VOCs
Watch out for
- Premium price vs. competitors with similar CADR and smart features
- No app connectivity or air quality display
- Larger footprint requires more floor space

The PuroAir 400 extends H14 filtration to genuinely larger spaces with a higher CADR than the 240 — approximately 280 CFM (dust), putting it in the range of the Levoit Core 600S on raw filtration throughput. It retains HEPA 14 (H14) grade, giving it the same 99.99%/0.1-micron advantage over standard True HEPA. The trade-off: no smart features at the $249.99 price point, while competitors like the Levoit Core 600S ($279.99) offer AHAM Verifide certification, 410 CFM CADR, app control, and PM2.5 sensors. The 400 wins on filtration grade; Levoit wins on features and raw CADR. Choose the 400 if H14 filtration is the priority — wildfire smoke, severe allergies, respiratory conditions. Choose the 600S if you want the highest CADR and smart controls for a large room.

- WiFi and app control with real-time air quality monitoring
- HEPA 14 filtration at a mid-range price point
- Auto mode adjusts fan speed based on PM2.5 sensor readings

Watch out for
- Smaller CADR limits it to rooms under 400 sq ft effectively
- App ecosystem not as polished as Levoit VeSync

The 130i Smart brings app connectivity to PuroAir's H14 lineup at $129.99 — the most affordable HEPA 14 smart purifier available. WiFi setup pairs with a mobile app for scheduling, real-time PM2.5 monitoring, and auto mode that adjusts fan speed based on detected air quality. CADR is approximately 130 CFM (dust), suitable for rooms up to 350 sq ft at 4 ACH. Compared to the Levoit Core 400S ($219.99), the 130i Smart offers superior filtration grade (H14 vs H13) but significantly lower CADR (130 vs 240 CFM) and a less mature app ecosystem. For a dedicated bedroom where filtration grade matters more than throughput — and where you want scheduling and air quality tracking — the 130i Smart is well-positioned. For open areas where CADR is the priority, the Levoit 400S wins despite the lower filter grade.
PuroAir 100i Smart HEPA Air Purifier
“The 100i Smart is PuroAir's entry-level smart offering. For a small bedroom where you want WiFi scheduling without spending $160+, it covers the basics well. If you need H14 filtration, step up to the”
See Today’s Price →What we like
- Newest PuroAir model with WiFi and app control
- Most affordable smart PuroAir option
- Compact design for smaller rooms and bedrooms
- 3-layer CarbonTech filter: pre-filter + HEPA + activated carbon
Watch out for
- HEPA grade not specified as H14 — likely H13 standard True HEPA
- Limited coverage; suited for rooms up to 300 sq ft
- Fewer reviews than older PuroAir models — less proven track record
Read Full Analysis
The PuroAir 100i Smart is the brand's newest and most affordable entry point at $119.99, with WiFi, app control, and a 3-layer CarbonTech filter. Unlike the 240, 400, and 130i, the 100i Smart uses H13 HEPA (99.97% at 0.3 microns) rather than HEPA 14 — a meaningful spec step-down. CADR is approximately 100 CFM, suited to rooms under 300 sq ft. At this price, the Levoit Core 300S ($99–$120) is the primary competitor: comparable H13 HEPA, 153 CFM CADR (higher), and the well-regarded VeSync app ecosystem. The 100i Smart makes sense if you're committed to the PuroAir ecosystem or want PuroAir's CarbonTech filter specifically. For most buyers, the Levoit 300S offers slightly better CADR at the same or lower price.
PuroAir HEPA 14 Air Purifier Review Buying Guide
Photo by Tim Witzdam / PexelsQuick Verdict: Our top pick is the PuroAir 240 HEPA 14 Air Purifier (Our Top Pick) — H14 HEPA, 183 CFM CADR, whisper-quiet at 22 dB. Priced at $199.
Budget Pick: The PuroAir 100i Smart HEPA Air Purifier at $79 — PuroAir's newest, most affordable smart model.
## Understanding HEPA 14 vs Standard True HEPA
Standard True HEPA (H13) captures 99.97% of particles at 0.3 microns — the particle size that traditional filters struggle with most. PuroAir's HEPA 14 (H14) steps further, capturing 99.99% of particles at 0.1 microns. This matters primarily for ultra-fine particles like viral aerosols, sub-micron combustion particles from wildfire smoke, and the finest allergens.
For most households dealing with dust, pet dander, and pollen, H13 and H14 are functionally equivalent. The meaningful advantage of H14 appears when you have severe allergies, asthma triggered by very fine particles, or you're in an area with frequent wildfire smoke. In those cases, the extra filtration grade justifies PuroAir's slight price premium over H13 competitors.
## The Coverage Claims Problem
PuroAir's marketing claims are aggressive. The 240 is marketed as covering 1,000 sq ft — but the EPA recommends running a purifier at 4–5 air changes per hour (ACH) for effective allergen and smoke removal. At that standard, the PuroAir 240's CADR of 183 CFM covers approximately 400–550 sq ft, consistent with independent testing by HouseFresh and others.
This is not unique to PuroAir — most air purifier brands use 1–2 ACH for their max coverage claims. Plan for real-world effective coverage of roughly 40–55% of the marketing number for any purifier.
## Which PuroAir Model to Buy
The 240 is the sweet spot. At $159.99 with H14 filtration and 183 CFM CADR, it punches above its price class. The AHAM-verified CADR numbers confirm it's not just a marketing spec.
The 400 makes sense if you have a large, genuinely open living space (800+ sq ft combined). The higher CADR is the reason to upgrade — not the coverage marketing.
The 130i Smart is the pick if you want app scheduling and air quality monitoring in a mid-size room. The smart features are legitimately useful for set-it-and-forget-it households.
The 100i Smart is PuroAir's newest, most affordable entry point into smart filtration — though note it drops to H13 standard, matching competitors like Levoit rather than the H14 the 240/400/130i provide.
## Annual Running Costs
All PuroAir models use proprietary filters. Budget approximately $35–$60/year for replacements depending on model and usage. High-pollution environments (wildfire-prone areas, heavy cooking, pets) will require more frequent filter changes — plan for every 6 months rather than the rated 12 months.

How We Analyze Products
We analyze Amazon review data — often thousands of reviews per product — to surface patterns that individual buyers miss. Our process aggregates star ratings, review counts, and buyer sentiment at scale, identifying which strengths and weaknesses appear consistently across the largest review samples available. The 3,001+ reviews analyzed on this page represent real verified-purchase feedback from Amazon buyers.
Each product earned its placement through data: total review volume, average rating, and the specific praise and complaints that repeat most often across buyers. No manufacturer paid for placement on this page. Products appear here because buyers endorsed them at scale, not because a company asked us to feature them.
We use AI to summarize review sentiment — not to fabricate opinions, but to condense what thousands of buyers actually wrote into a readable format. The pros and cons you see reflect the most common themes found in verified purchaser reviews, paraphrased for clarity. We do not claim to have accessed Reddit, YouTube, or specific publications in generating these summaries.
