Dimensions	19 × 12.5 × 12.5 (height × width × depth). Blueair doesn't give units, but the figures fit inches. It weighs 7.8 lb.	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).
Installation	No installation. It has a 360° intake and a top air outlet, and Blueair says you can place it anywhere. Wi-Fi and the Blueair app add schedules, an on/off timer and filter tracking. The product page gives no wall clearance.	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.
Materials	A washable fabric pre-filter in four colors (Sand, Stockholm Fog, Moss, Limestone) covers the main filter. The standard Particle + Carbon filter pairs a particle layer with activated carbon that Blueair says traps light household odors. Blueair calls the system HEPASilent and says it combines electrostatic and mechanical filtration. SmokeBlock and AllergenBlock filters fit in place of the standard one.	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.
Warranty	One year against defects in material or workmanship. Register within 60 days, in your Blueair account or the app, and it extends to three years. Filters are covered for 30 days. Claims require that you've replaced filters on Blueair's schedule, with proof of purchase. Coverage is for the original owner only, and a unit exchanged during the extended term may be refurbished. If you bought it from another seller, you'll need proof of purchase. Blueair also says warranties aren't available from third-party resellers but doesn't define the term.	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.
Returns	30 days from purchase for items bought directly from Blueair, with a prepaid return label. Filters and pre-filters taken out of their plastic wrap can't be returned. The $5 flat shipping charge and any other shipping charges aren't refunded. Processing takes 10 to 14 days. The refund then reaches your original payment method in 3 to 5 business days.	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.
