Is the Lasko Desktop Air Purifier worth it?

For a desk, nightstand or small bedroom it is a cheap way to get HEPA and carbon filtration. It is not a substitute for a full-size purifier in a large room.

How much area does it cover?

Lasko rates it for 56 square feet, with a CADR of 38 CFM. That is roughly one small room or a corner of a larger one.

Does it produce ozone?

It is ARB certified to comply with federal ozone emissions limits. The ionizer can be turned off if you prefer not to use it.

Lasko lists 43.9 dB. Low speed is quiet enough for a bedroom; the top speed is noticeable at close range.

What filters does it use?

It uses a pre-filter, an activated carbon filter and a Lasko HEPA pleated filter. The grill is removable for access.

When is the best time to buy it?

At $41.99 at Best Buy as of November 6, 2026, it is near the bottom of its recent range. Waiting for a holiday sale is unlikely to save much more.

Our take on the Lasko Desktop Air Purifier

The Lasko Desktop Air Purifier is a small three-stage unit for desks, nightstands and other tight spots. It combines a pre-filter, activated carbon and a HEPA pleated filter, and adds an ionizer mode, a digital display, a timer and automatic shutoff. Its 38 CFM CADR and 56-square-foot coverage suit a single room corner, not an open living area. At $41.99 at Best Buy as of November 6, 2026, it sits at the low end of its recent price range across the 7 stores that carry it new.

What reviewers say

4.6 / 5113 ratings

Rated 4.6 out of 5 from 113 ratings, the Lasko Desktop is generally liked as a compact, quiet-enough unit for a desk or small bedroom. Owners value the simple controls and the noticeable drop in dust and odors in a small space. The main reservations are its limited coverage and the cost of filters.
