### 1/5 — No alerts

*2026-08-21, version 2.7.1*

I haven’t received any alerts at all

### 4/5 — Unavailability of Smart Filters

*2026-08-15, version 2.7.1*

I have not been able to purchase a 2500 MPR filter with the smart sensor

### 5/5 — Filter tool app

*2026-08-11, version 2.7.1*

A great tool to have.

### 5/5 — Filter

*2026-07-27, version 2.7.1*

I would not buy any other filter lets me know in the app when it needs to be replaced I can track everything that’s going on with my filter Thank you

### 5/5 — 3M Filtrite Smart Filter

*2026-07-26, version 2.7.1*

Great product with greatly increased performance over cheap card board Egg crate filters complete with a wonderful app to monitor filter change timing.

### 1/5 — Waste of an app and excessive ewaste

*2026-07-18, version 2.7.1*

1) The “sensor” they attached to the filter is just a dumb countdown timer, interferes with the tight clearances in the filter holder, and is just more toxic ewaste. 

2) There is no reason to give Filtrete access to my private data when a simple reminder set in my phone does the same thing.

The app claims to actually measure filter use and airflow.  I removed one of the sensors and put it in a plastic bag where there is no airflow and no filter usage to measure. It is still recording filter use.  So far it’s recorded 6% use in 4 days. At this rate it will have me replacing the filter in a little over 2 months.

### 2/5 — Buggy or no longer working with barcode scans?

*2026-07-07, version 2.7.1*

I noticed on the back of the packaging that you could start a 90 day replacement reminder using their app. After downloading it went to scan this filter’s packaging barcode, as instructed, and gave an error message saying “Try again” over and over. I’ll just keep setting a reminder in my phone to swap them out. 

Great app in concept but not if it’s faulty.

### 5/5 — Quality Products

*2026-07-03, version 2.7.1*

Well built and does a fantastic job.

### 3/5 — Good app but still needs work

*2026-06-28, version 2.7.1*

We’re almost a year into iOS 26 and Liquid Glass but the Filtrete Widget still fails to display anything when Liquid Glass is enabled on the Home Screen.  Would be nice to have the widget work with a feature of the OS.  There were several apps that had issues early on but every one of those apps have fixed this issue and most of them months ago.  Please address this before iOS 27 is released!

### 5/5 — Awesomeness

*2026-06-13, version 2.7.0*

Awesome!
