Review on 🌬️ DuraBasics 13 HEPA Filters for HPA300 Honeywell Air Purifier and HPA300 - 3 HEPA Filters & 4 Pre-Cut Activated Carbon Pre Filters - Replacements for Honeywell Filter R and HPA300 Filter by Lance Jenkins

The product is an exact replacement for OE filters. The filter fits perfectly and is easy to assemble. The pre-filters should be tailored to your specific device. This is easy to do with regular scissors - just use the pre-filter to be replaced as a template to cut out the new pre-filter. easy to install, how do you know that the main filter is really a HEPA filter and that it really does what it says on the tin? We don't know exactly, but we also don't know if the manufacturer's original filter keeps what it promises (!). We just have to trust the production. I would buy it again without hesitation.
