Description
xKeep your Holmes and Bionaire air purifiers performing at their best with the IOYIJOI Filter Replacement Kit. This thoughtfully designed set brings together a four-filter core and eight booster pre-filters, so you can maintain efficient filtration and steady airflow between full replacements. The kit is built to fit Aer1-ready models and to replace the A, D, and K filter families, offering flexibility for different units in your home.
The IOYIJOI kit embraces practical details you’ll notice in daily use. The four replacement filters catch larger particles and help preserve the purifier’s filtration system, while the eight booster pre-filters provide an extra layer of defense against common household dust and odors. With spare filters included, you can rotate changes to suit your schedule and keep your purifier ready for action whenever you need it.
