Main trade-off	Levoit publishes one CADR and one power figure, and no independent listing for this model could be confirmed.	It covers only one small room, and it has three manual speeds with no air sensor or auto mode.
Key specifications	CADR: 250 CFM; Levoit gives one figure, not separate smoke, dust and pollen ratings Room size: 388 ft² at 4.8 air changes an hour; 1,862 ft² at 1 Noise: 23 to 54 dB; 26 dB or less in sleep mode, per the filter page; no per-speed figures Power draw: 50 W rated (51 W in the manual); no high, low or standby figures Filters: Washable pre-filter plus one combined main and activated carbon filter Filter life and price: 6 to 12 months; $49.99 standard, $59.99 Pet Allergy or Toxin Absorber, $64.99 Smoke Remover Controls: Auto, sleep, four fan speeds and a timer on the unit; pet mode, quiet auto, schedules and filter tracking in the VeSync app Size and weight: 15.6 × 8.5 × 19.8 in; 13.2 lb	CADR (smoke, dust, pollen): 122, 123 and 123 cfm Room size: 189 ft² at 4.8 air changes an hour (one change every 12.5 minutes) Noise: 24 to 49 dB in the spec table; 22 dB on low and 44 dB on high in the FAQ Power draw: 16 W, a single figure with no low or high Filters: One Particle + Carbon filter behind a washable pre-filter Filter life and price: About 6 months; $23.99 per filter, $6.99 per pre-filter Controls: Three manual fan speeds and a filter-change light; no air sensor Size and weight: 13.4 × 7.9 × 7.9 in; 4.2 lb
Exact variant	Vital 200S-P, Black / LAP-V201S-WUS	US model, store item 109994, with one Particle + Carbon filter and an Arctic Trail pre-filter
Dimensions	15.6 × 8.5 × 19.8 in (width × depth × height), or 39.6 × 21.7 × 50.2 cm. It weighs 13.2 lb (6 kg).	13.4 × 7.9 × 7.9 in (height × width × depth). It weighs 4.2 lb.
Installation	No installation. It sits on the floor or another flat, stable surface and runs from the included AC adapter (24 V, 2.5 A). The manual asks for at least 15 in (38 cm) of open space in front. Keep it away from curtains, damp spots and heat sources, and 5 ft from where oxygen is in use.	None. Plug it in and it blows clean air out the top. Blueair's page links no manual, so it doesn't say how much wall clearance it needs.
Materials	It has three stages: a washable pre-filter, a main filter and an activated carbon layer for smoke, odors and fumes. Levoit says the main filter traps 99.97% of particles at 0.3 microns. The main and carbon stages come as one replaceable filter. Levoit calls that filter HEPA-grade only in sleep mode. The carbon is FSC-certified wood carbon. The manual doesn't mention an ionizer or UV lamp. It carries a California Prop 65 warning for lead.	A single Particle + Carbon filter sits behind a washable pre-filter. Blueair says the filter captures PM2.5, pollen, dust mite allergen and pet dander allergen. The carbon is aimed at light household odors such as smoke and cooking. Blueair calls the system HEPASilent, a mix of electrostatic and mechanical filtration. Pre-filters come in Arctic Trail, Night Waves and Winter Reed.
Warranty	2 years from the original purchase date, covering defects in materials and workmanship. Registration isn't required, and the warranty doesn't transfer to a later owner. Filters count as normal wear and aren't covered, and neither is commercial use. Only units bought from Levoit or an authorized seller qualify. Claims need the invoice and order ID, with the serial number and date code intact. Levoit decides whether to repair, replace or refund.	One year from purchase, or two if you register. Blueair's warranty page gives 60 days to register, in your Blueair account or the app. That page doesn't name the 511, so the two-year term comes from the product page. You need to replace filters on Blueair's schedule and keep proof of purchase. Coverage is for the original owner only, and warranties aren't available through third-party resellers. In the first year a defective unit is exchanged for a new or equivalent one. During the registered extension, the replacement is refurbished. Coverage ends if the unit leaves the continental US or Canada. Filters are covered for 30 days.
Returns	Levoit offers a 30-day money-back guarantee on direct purchases, counted from delivery. The unit must go back in its original packaging with all accessories, and excessively worn or used items are refused. Levoit emails a prepaid label once it approves the return, and you have 15 days to ship it. The policy doesn't say whether opened filters can be returned.	30 days from purchase for items bought directly from Blueair, sent back with Blueair's prepaid label. Filters and pre-filters that are used or out of their plastic wrap can't be returned. Shipping charges, including the $5 flat rate, aren't refunded. Blueair takes 10 to 14 days to process a return. The refund then reaches your original payment method within 3 to 5 business days.
Unresolved questions	Whether AHAM's Verifide directory lists it, and with which smoke, dust and pollen CADR Whether CARB certified it; the readable part of CARB's list didn't reach it Which pollutant the 250 CFM figure refers to Power draw at each fan speed and in standby Noise at each fan speed Whether the $59.99 Pet Allergy or $64.99 Smoke Remover listing includes one filter or two Which color ships from the $189.99 listing Whether opened filters can be returned	Whether it's listed in AHAM's Verifide directory or Energy Star's product finder; neither directory could be read Whether CARB has certified it; the part of CARB's list that loaded showed four other Blueair models Power draw on low, and which speed the 16 W figure refers to Noise at speed 2 Whether the electrostatic part of HEPASilent gives off any ozone Wall clearance and other setup guidance from the manual
