[Health] ResMed Hypoallergenic Filter After 1 Month

RE: ResMed Hypoallergenic Filter After 1 Month
If you have a forced air central heating and cooling system you can use a MERV 11 or higher air filter and trap particulates and viral respiratory droplets down to a sub-micron level. That will help everyone in the household breathe cleaner air. They can be very economical to buy from some manufacturers who discount heavily and sell direct on line.

The additional benefit of the hypo filters are absolutely not to be dismissed. I can't fathom in any scenario outside of a bubble that folks would opt not to use them.

Very true.

I'm not sure how difficult it is to buy a HEPA filter where you live, but I just wrote a review on one we recently bought. And I love it. We have had a PM2.5 AQI of up to 270 recently with the local wildfires, and indoors our Levoit 400S would report a 30 AQI when first turned on. And you could smell the smoke. It would drop to 1 to 3 easily in less than an hour. And no more smoke smell.

Thanks for the review! Very helpful.

An air purifier is an expensive purchase considering the average income in my region, and is limited to a selection of Chinese brands (e.g. Xiaomi.) Even so, customer support and warranties are non-existent; replacement air filters are counterfeits of questionable filtration efficacy and HEPA "certification" even if the one that comes with the device is the real thing. I'm trying to find a solution that has some semblance of a "guarantee" of availability of genuine replacement filters. That's the primary concern.

This is a great idea. Central air conditioning in my region is rare, but I have purchased MERV 13 filters living in the US before, and it made a noticeable difference to the air quality in the house, particularly with pets present. Most regions in the US, though, have better air quality and home insulation than I have here to start with, not to mention central air filtration.

Unfortunately, members of the household (particularly those who are older) get uncomfortable if all the windows and doors to the rooms aren't left completely open 24/7 for "ventilation." There's no way even putting an air purifier in each individual room and cranking them up to maximum would make a difference, to say nothing of the power consumption.
