Woosh Smart Air Filter Review: No More Guessing

“It’s a useful way to monitor the pressure drop across the filter, and it’s a good way to know when it’s time to change the filter, otherwise there’s a lot of guesswork,” Lee says. The typical three-month replacement recommendation is based on the assumption that your HVAC system is running at 20 percent capacity (about five hours per day), she says. A lot of this depends on your climate, Lee says Recent study It found that the average HVAC uptime for 20 homes over the course of a year in Toronto was 10 percent, meaning those people would be able to replace their filters less frequently.

As for the MERV 13 verdict, Lee says a higher flow resistance will make the HVAC fan work harder. Depending on your system, the fan can Stop Work hard, reducing airflow and potentially damaging the cooling coils. However, a higher MERV rating does not equal higher flow resistance. It depends on the quality of the filter, as Lee says she has seen MERV 13 filters with lower flow resistance than MERV 8. Ultimately, Lee says the key factor is the age of your HVAC system.

“If this is a relatively new system that’s in good condition, and you’ve been using MERV 8 filters without any problem, I don’t think there’s going to be any problem using MERV 11 or MERV 13 or even MERV 14 filters just because even if there’s a difference in The flow resistance, it’s relatively small.” “I think most systems will be able to handle that, especially if you don’t change your filter all year.”

People using older systems should be careful, as they may not be able to handle high-efficiency filters at all. She suggests listening to the sound and feeling the flow coming from the cooling and heating vents in your home.

The good news is that the Woosh Smart Filter can detect problems in your HVAC system. The company says it can identify early signs of a file freeze, which if left untreated can cause irreparable damage. It manages this by checking pressure drop and flow rate along with temperature and humidity levels.

Fortunately, using the MERV 13 filter did not appear to cause any adverse effects on my system and I did not receive any notifications about issues with my HVAC system. My only concern is that, according to the app, I… Still I don’t need to change my filter even though it’s been nine months since I installed it. My wallet is happy, but everything I’ve heard and read about the filters says I should have changed them by now.
