## Specifications

- Water panel model: 35
- Compatible humidifier models: 700, 700A, 700M, 760, 760A, 768

## Before you buy

- The listing describes this as a complete kit for the named models. Confirm your humidifier's exact model before ordering, since compatibility is specified only for 700, 700A, 700M, 760, 760A and 768. The water panel measurement is written as 13" H x 10" W x 1.75" W, while product dimensions are listed as 1.75 x 10 x 13 inches, so the panel's last dimension label is inconsistent.

## A good fit for

- Owners of AprilAire 700, 700A, 700M, 760, 760A or 768 humidifiers seeking a maintenance kit with a replacement water panel.
- Buyers who need several listed service components and an owner's manual in addition to the panel.

## Less suited to

- Owners of humidifier models not named as compatible in the listing.
- Shoppers who need only a water panel and do not need the other kit components.

## Customer feedback

Customer feedback reports good fit, straightforward installation and replacement components that customers describe as matching the original parts. Some also frame the kit as a way to restore a humidifier rather than replace it. Those points are relevant for owners of the listed compatible models, though fit still depends on matching the exact model. Overall ratings skew strongly toward five-star responses, but ratings alone do not establish why customers gave them.
- Positive themes: Customers report that the filter fits well and is easy to install.
- Positive themes: Feedback describes the replacement parts as matching the old components.
