My experience is mainly in central HVAC systems and I mostly agree that filters could have a much long service life. However, I’ve seen significantly shorter life via fine particulate via the use of tap water in humidifiers. Ime this will clog a MERV 13 filter in a few weeks. If you can afford a manometer (~$100) capable of reading increments of IWC ~.1, testing pressure is quite simple and many more people would benefit from adding this type of measurement to their skillet! I’m happy to provide further guidance!
Yeah if $100 can save you even just 3 filter replacements, that sounds like a good investment. Maybe I should do this myself. For now, I will just hope motor sound + my intuition/tacit knowledge of air purifier air flow is enough for me to realize when a filter definitely needs replacing. Thanks Jesse!
