This replacement filter fits the Aprilaire 400 humidifier and is cheaper (including shipping) than purchasing from aprilaire’s website (even though they have free shipping).
That being said, this replacement filter is grossly overpriced for what it is. Clearly a profit center for Aprilaire.
I have ordered this part before and have had no issues with this seller. Product arrived quickly.

There’s not much to say about the filters. They are the manufacturer’s replacement unit and do their job. The service from Filters-Now was very good with fast delivery. I won’t hesitate to order from them again, either directly or through Amazon. The price seems high for a simple paper and metal filter, but it’s clearly a profit center for the manufacturer. The price from this vendor was much better than from others I found.

In general I find these filters cost far too much. Decent price, decent service from this vendor.
