03QuestionsBefore you order

Before you order.

Straight answers. Anything else, email support@thinkcrucial.com.

Q.01Is this made by Hunter?

No. It's a compatible replacement made by Think Crucial. It isn't made, sold or endorsed by Hunter, and Think Crucial isn't affiliated with Hunter.

Q.02How many filters do I get?

Two, so the next change is already on the shelf.

Q.03Does it fit Hunter models that take 30930 or 30963?

No. This replaces part 30931 only. We sell a separate 30963 filter.

Q.04What if it doesn't fit?

Fit guaranteed: if it doesn't fit the model we list, email support@thinkcrucial.com within 30 days of delivery with your order number and model number. We send a prepaid return label and refund you in full, even if you opened it to test the fit. Changed your mind? Return it unused, in its original packaging, within 30 days of delivery.

Q.05Is there a subscription?

No. You buy when you need it. Nothing renews and nothing auto-ships.

Q.06When will it arrive?

Free U.S. shipping on every order, from a U.S. warehouse. Ships the same business day when ordered by 2pm ET. Arrives in 2–5 business days.

04Who makes this

We make what we sell.

Think Crucial started in 2007 at a family vacuum repair shop. Today we're a U.S. company in Hollywood, Florida, making aftermarket filters, bags and parts built to fit the machines you already own. Most people can fit the part themselves. They just need the right one, and a way to check it first.
