Right away, they’re bad at modern air filtration altogether
I think that it’s easy to convince yourself that it’s a good proposal to regularly look for the cheapest choice. If you’re buying food ingredients, this might be a good task for getting by and simply being happy with what you eat. However, there are other situations where being cheap is terrible. I heard a bad story recently from a coworker whose sibling had to get dental surgery following a car accident. Because of the botched task administering novocaine shots while I was under during the procedure, he has serious nerve mangle in his mouth and lips that is never going away. It affects the way he talks and the way he eats, and it kills myself and others when I reflect about it. Sadly, someone gave him awful advice and told him to find the cheapest professional to hire, and it turned out in the worst possible way. I don’t gamble with my health, not the least with my lungs. Some people are totally indiscriminate about the things they’re willing to subject their organs to, sporadically simply mold and bacteria in their homes from a lack of regular cleansing. Other times people are cheap with things like disposable a/c filters. There’s a growing trend right now of people buying washable air filters, but they’re being led on by false information. At best, a brand new washable air filter has a MERV level of 4, which is entirely horrible compared to my allergen filters with a MERV level of 12. Right away, they’re bad at modern air filtration altogether. But once you start washing them, they are a breeding ground for gross mold and mildew spores as it’s next to impossible to get them to dry out after each cleaning procedure.
