What to know before buying

Listing details to confirm

The listing gives a nominal size of 20 x 20 x 4 inches but lists dimensions of 4"L x 21.38"W x 18.87"Th. Check the purifier model and filter fit, especially for competitive models that require a 4898 Upgrade Kit. The listed weight is 0.27 g, which is unusual for a filter, so confirm it if weight matters. The description claims up to 12 months of filter life, while customer feedback is mixed on how long it lasts. These details are inconsistent or unconfirmed in the listing, not established product defects.
