Model: The AprilAire 401 is a replacement media filter for AprilAire and Space-Gard 2400 whole-house air purifiers. Its MERV 10 rating and nominal 16 x 25 x 6-inch size suit buyers replacing the original media, but confirm compatibility and fit dimensions before ordering.

## Before you buy

- The listing gives dimensions of 7.47"L x 28"W x 17"Th but separately calls 16 x 25 x 6 inches the nominal size, which it says is not the actual size. Filter life is also inconsistent: one claim advises annual replacement or up to 12 months, while another says one to two years depending on system operation. Confirm the suitable model and replacement interval for your setup.

## In the box

- 1 401 filter media (Included)

## A good fit for

- Owners of AprilAire or Space-Gard 2400 purifiers seeking the listed 401 replacement media.
- Buyers who want a single MERV 10 filter with bonded glass fiber construction.

## Less suited to

- Owners of purifier models other than the listed 2400 models unless compatibility is confirmed.
- Buyers seeking the separately sold 1413 upgrade kit or its 413 filter media.

## Customer feedback

Customer feedback highlights easy installation, reported fit with compatible air conditioners, and perceived dust reduction. Reports also raise concerns about flimsy construction and media tearing during installation. These comments matter when handling the pleated filter, even though the listing specifies bonded glass fiber media and MERV 10 filtration. Customer reports of replacement intervals vary, so they do not settle the listing's conflicting service-life guidance.
- Positive themes: Customers report easy installation and a good fit in compatible systems.
- Positive themes: Some customers say it works well with their air conditioners and reduces household dust.
- Negative themes: Some customers describe the filter as fragile and say it can tear during installation.
- Negative themes: Build quality receives mixed feedback, with some customers describing it as cheaply made.
- Mixed feedback: Customer-reported filter life varies, and feedback does not resolve the listing's differing replacement interval claims.

## Frequently asked questions

### Which purifiers is the AprilAire 401 listed for?
The listing identifies AprilAire 2400 and Space-Gard 2400 whole-house air purifiers. Check the model label on your purifier before ordering.
### What is the filter's actual size?
The product is described as nominally 16 x 25 x 6 inches, and the listing states that nominal size is not the actual size. A separate dimensions field gives 7.47"L x 28"W x 17"Th, so verify fit with your purifier and existing filter.
### How often should the filter be replaced?
The listing is inconsistent. It recommends annual replacement and also says up to 12 months, while another statement gives a one-to-two-year range depending on system operation. Follow the guidance applicable to your equipment and use.
### Does the filter include the 1413 upgrade frame?
No such inclusion is stated. The listing describes the AprilAire 1413 upgrade kit as sold separately.
