Innovative Design for Enhanced Durability: Departing from the traditional paper frame, we've introduced a robust ABS frame. Its inner serrated structure securely holds the filter paper in place, completely eliminating concerns about filter collapse or deformation during use. This not only extends the filter's lifespan but also ensures a consistently better filtration effect, providing you with cleaner air for longer

User - Friendly Operation: Thanks to the quick - locking buckle design of the ABS frame, disassembly is a breeze. The pre - fixed pleat spacing on the refill filter paper simplifies the filter - changing process, allowing you to complete the replacement with minimal effort. It's a hassle - free experience even for first - time users

Cost - Effective Solution: The reusable ABS frame significantly cuts down on production costs. This cost - saving measure directly benefits every family using the OlitAir filter, making clean air more affordable without sacrificing quality

Exceptional Filtration Performance: Our refill filter papers are crafted from high - quality melt - blown composite materials. They feature high - efficiency filtration and low wind resistance. This means they can effectively purify indoor air while reducing the energy consumption of your equipment. Depending on your specific usage environment, we recommend replacing the refill filter paper every 30 to 90 days to maintain optimal performance
