Review on 🧹 HIMrHEPA 2 Pack Vacuum Filters: Compatible with Shark APEX AX910 AX912 QU922Q - Boost Cleaning Efficiency & Savings with Comparable Part # XPRHF910 & XFF680 by Beth Westra

Apex AX912 and the price is right. However, note that it does not include a HEPA pre-filter, which is also part of my vacuum's filtration system. The pre-filter is a thin, washable fabric filter in a plastic frame that fits directly under the HEPA filter. I wrongly assumed it would be included as part of the HEPA filter. Not a big problem as it's easy to clean and doesn't need to be replaced regularly. But over time it wears out and needs to be replaced. Be aware of this and don't assume like I did that it will be part of a HEPA filter.
