Ahh, people with HVACs, how I envy them. None available for an apartment, unfortunately. There are several things you want covered, and nothing short of a full HVAC covers them:
- heating/cooling
- ventilation (bring air from outside to lower CO2 and VOCs
- ideally, heat recovering system for ventilation
- air purifier for P10, P2.5, pollen and so on
- if I could pay extra for a professional humidifier that doesn't need refiling, I definitely would. Not a must, but a VERY nice to have.
You can find aircons with "hepa" filters (I wouldn't trust them to cross the street though). You do NOT find aircons with ventilation. Yeah, they all say they do ventilation, but that just means they work as a fan, they do not bring air from the outside. You can find air purifiers, even very good ones, but they purify the air already inside - open a window and it's full reset. Plenty of good air humidifiers, if you have the patience to refill them every two days.
I sometimes fantasize what it would be like to cobble a system together. Most of what's missing is a heat recovery ventilation, but that's awkward as fuck to add in an apartment.
- lazyjones 6y agoYou can also find separate air purifiers for your apartment, e.g. https://www.iqair.com/room-air-purifiers/gc-multigas https://www.iqair.com/room-air-purifiers/gc-multigas But, to be honest, I prefer opening the windows more often.
- WalterBright 6y agoOne thing you can do is: 1. get a box fan 2. get a furnace HEPA filter 3. tape the filter over the fan 4. turn it on!

- kube-system 6y agoYou can skip step 3. The negative pressure on the inlet side of the fan is plenty enough to hold the filter to the side of the fan. The common square box fans sold in North America work perfectly with a 20x20 furnace filter.
- p1mrx 6y agoI taped a window shut to install a portable A/C, but it feels wrong to run it at night when the outside air is colder than inside. It can cool relatively efficiently in that case, so it doesn't need to run for long, but ventilation would make it free.
- Cactus2018 6y agoI bought a Winix air filter from CostCo for my apartment. I am amazed at how much 'material' is captured on the permanent pre-filter every two weeks. The pre-filter needs to be rinsed every two weeks.
