Ive had the BMS filters for three years without issue 🤷‍♂️ Not sure what problems people have had but Ive been in terrible weather, auto car washes, etc and have no complaints

Well we are in one of the biggest downpours right now with over 107mm of rainfall today alone and without these as shown earlier Its cheap insurance.

How much are possible HVAC system issues worth if water got in ?

Also those BMS filters look ugly so it has a dual purpose.

No one is telling you to get it but its available if you want it, the possibility is there if you choose to run these.
