Air filter
I have been using these filters for 5 plus years and they work very well.

Replacement filters of poorer quality construction and less filter area.
Had purchased Crucial Vacuum bags & was hoping for a similar quality item. BUT the trend of replacement filters of poorer quality construction and less filter area occurs with this brand. These 30931 Crucial filters had less filter area [14 pleats] than the M****t filters [18 pleats] I'd bought & the cardboard frames are thinner & flimsier. P******g also makes a better HEPA filter, BUT not for this model. Have 30 days to decide if I'm going to send them back...If I can find an equivalent P*****g or M****t filter, then I probably will.

If your label shows a different model, compatibility isn't confirmed: email support@thinkcrucial.com with the model number before you order. If a listed model doesn't fit, we send a prepaid return label and refund you in full.
Q02Is this an original Hunter part?
No. It's an aftermarket filter made by Think Crucial to fit the models listed. Think Crucial is not affiliated with Hunter. We make what we sell.
Q03What if it doesn't fit, or I change my mind?
If it doesn't fit the model we list, we email a prepaid return label within 30 days of delivery and refund you in full; opened to test the fit is fine. Changed your mind? Return it unused in its original packaging within 30 days of delivery. The return label is free for these too.
Q04When will it arrive?
Shipping to U.S. addresses is free on every order. It ships from our fulfillment center in 1–3 business days and arrives in 3–7 business days.

No. You buy one when you need one. Nothing renews and nothing auto-ships.
We make what we sell.
Think Crucial started in 2007 at a family vacuum repair shop. Today we make aftermarket filters, bags and parts built to fit the machines you already own, plus our own descalers and cleaners. Most people can fit the part themselves. They just need the right one, and a way to check it first.
