25 Series Flush Mount Dual Carbon Monoxide/Propane Alarm with Trim Ring - White - 12V Hard Wire

The Safe-T-Alert 25 Series combination CO/Gas Alarm combines a powerful, compact system that detects both Carbon Monoxide (CO) and explosive Propane (LPG) gas. The 25 Series uses the latest microprocessor technology, combined with two electronic self-cleaning sensors that operate independently. The combined unit can detect both CO and explosive gases simultaneously.

This detector is listed as a CO and Propane gas detector for RV use. Other explosive gases, such as Acetone, Alcohol, Butane, and Gasoline, may cause false alarms.

To prevent false alarms from brief “puffs” of gas, the detector has a recheck cycle before alarming. If high levels of gas remain during the recheck cycle, the detector will alarm.

The electronic CO sensor in your SAFE-T-ALERT CO alarm is very sensitive to CO gas. It will not react to safe levels of most other gases.

Features:

  • This unit comes with a trim ring to cover existing screw holes and fit newer units into previous installation cutouts.
  • Patented Double-Duty Alarm. Upgrades single 12 Volt Propane Gas alarms to a dual alarm that detects both Propane Gas and CO.
  • Space Saving. Compact design for RVs.
  • Designed for the Rugged RV Environment. Ideal for Class A Motor homes, Class B Van Campers, Class C Mini-Motor Homes, Travel Trailers, Fifth Wheels, Truck & Folding Campers.
  • Advanced Technology. The Alarm Mute button silences the alarm while the RV is ventilated. Rapid recovery sensor resets when silenced or reactivates the alarm if dangerous levels of Propane or CO remain.
  • Reliable. 12 Volt power means no missing or dead batteries to replace.
  • Approved. Meets RVIA/NFPA requirements.
  • Conforms to UL STD 2034 RV /1484 RV.

Great aftermarket filter
Size: 7.5" x 8.7" x 1.4"
Performance will be TBD but after a test air does smell a bit cleaner. It Fits a 2018 Subaru Impreza just like the OEM does. Material is significantly better as well. The only thing that will cause confusion is the arrow designation many are used to. The OEM will state which way the filter is to be oriented (up), and this aftermarket version designates which way airflow goes which is usually in the direction of the blower or engine bay (down). Keep that in mind. Otherwise, it’s so easy and such a good peace of mind maintenance item everyone should do and NEVER pay the dealer.

Works ok, but not perfect. Manage expectations.
Size: 7.5" x 8.7" x 1.4"
My goal was to reduce or eliminate bad particulate odors coming in from outside while driving, as drive through areas with high particulate pollution. Sure, recirc mode exists, but then cars fill up with CO2 quickly, and high concentrations of CO2 makes you drowsy and have slow reaction times, etc. So I looked into better cabin air filters. My Subaru has an easy-to-access cabin air filter. I learned how to properly change it via online videos, because the dealership wants over $50 just to change the filter, and it only takes a few minutes! The OEM filter I took out is not that good, and only meant for larger particulates, to protect the HVAC system. It reminded me of the cheaper (but not cheapest) furnace air handler filters. Placing this new filter in and testing it, it does block more airflow, which is to be expected from a finer filter. My car's blower has 7 running speeds (plus off), and I needed to turn it up one notch higher to get about the same airflow, versus the previous filter. The filter seems to work, somewhat. If behind a diesel truck, I still smell it. Same with cigarette smoke from a car in front. It doesn't block vape vapors at all, it seems. However, maybe I was expecting too much. The infographic for this filter clearly shows the size of particulate it can handle, which I appreciate very much. Diesel exhaust is a very fine particulate, smaller than this filter can filter. I also wonder if outside air is getting around the filter in the filter housing, since it just slides in, like a furnace air handler filter. It has a good fit though, in my car at least. What I need is an even finer filter, but that would likely block a lot more airflow. There are various manufacturers of high-end cabin air filters, but I don't know if they match or exceed the quality of this one.

Good as OEM
Size: 7.5" x 8.7" x 1.4"
2024 Sub Crostrek, it fit great. I was so worried, that I need to get the OEM filter, but I went with this instead. Today as I installed the new filter, it looks as good or better than the original. I get that there's more to it than looks, but the quality of the look and feel appear to be matching that of the original, perhaps i might suggest it's even better.

Great cabin filter at a super price.
Size: 7.5" x 8.7" x 1.4"
I trust Bosch for car parts, and for the price and ease of installation, I'd take it over the Subaru OEM part any day. This is an easy replacement that the dealer would charge x4 the price to do.
