Leemone 2 Pack Blue Pure 211i Max Air Purifier Replacement Filters - H13 True HEPA & Activated Carbon Filter - Compatible with Blueair Blue Pure 211i Max (F2MAX Alternative) - Perfect for Home, Office, and Allergy Relief

I was initially hesitant to purchase an off-brand filter for my BlueAir 211i Max air purifier. I rarely ever wish to compromise on quality by using a cheaper alternative. However, after installing the Leemone filter, I can confidently say that my skepticism was unfounded.Fit and Finish: The Leemone filter fits perfectly onto the BlueAir 211i Max. Some reviewers have said of other models that their filter was loose, but the one of the 211i is a snug and secure fit just like the original BlueAir filter. The build quality is also impressive. The filter looks and feels very similar to the genuine one, with no noticeable difference in terms of materials or construction.Performance: While long-term performance remains to be seen, the initial impressions are positive. The Leemone filter seems to be effectively cleaning the air in my room, and the air purifier operates as expected with no issues.Value: The most significant advantage of the Leemone filter is its price. It offers a significant cost savings compared to the genuine BlueAir filter (you get 2 filters for the price of 1 genuine filter), making it an incredibly attractive option for budget-conscious consumers.Overall: Based on my initial experience, I am very happy with the Leemone air filter for my BlueAir 211i Max. It offers excellent value for money without compromising on fit, finish, or initial performance. I highly recommend it to anyone looking for a cost-effective alternative to the genuine BlueAir filter.
