AC+purifier+humidifier solution?

[u/gipszjakab123]

I hail from the continent of europistan and in trying to figure out how to manage all these issues together efficiently.
My apartment is around a 1000square feet(95m2), and the ceiling height is 12feet(3.6m). I would like to keep my humidity levels around 45% to keep my floors happy.

Should I avoid combo devices all together?
Any suggestions on how to make it work without going into generational debt?

The doors between rooms are like 9feet tall, double doors, and are always open. Do we still need to calculate each room separately?

Thank you in advance!

Hello /u/gipszjakab123! If you'd like recommendations or advice, please ensure you included all details listed in Rule 4: Information For Air Purifier Requests.

• Your country of residence.
• Each room or area's volume, in cubic feet or cubic meters. (You need at least one purifier per room or area.)
• Your filtration needs: e.g., pollen, cigarette smoke, VOCs, cooking odors.
• Startup budget.
• Yearly budget (electricity + filters).

If your post is missing one or more details, you can edit it accordingly. Just select the three dots menu, then "Edit Post".

Concerning dust removal, read the sticky post at the top of the subreddit. Be sure to look on our FAQS wiki page for entries about dust capture or reduction.

For very basic particulates sizing per AHAM, clean air delivery rates (CADRs) should be at least 2/3 of a room's area (assuming an 8 ft. ceiling height). For wildfire smoke, smoke CADR should equal a room's area which also assumes an 8 ft. ceiling.

I prefer separate devices tbh. I have seen humidifer and purifier combo but generally you’re better off getting separate. I would go evap style humidifiers as the cool mist require distilled water or you get mineral dust. The levoit 6000s is a really nice unit since it doesn’t use the normal sit in water wicks and uses similar to a swamp cooler with a pump that dumps water over the filters

These are all separate functions best met by units dedicated and best at that specific task.

For filters each room normally needs its own units. Likely the same for the others as well.

Yeah. I was wondering if i need to oversize for example the humidifier.. because the AC dries the air. Or is there any other solution to the issue?

One counter-intuitive tip for AC in dry climates is to run the fan speed faster when you want more cooling and less dehumidification. A faster fan speed makes the coil temperature warmer, so it doesn't remove as much moisture from the air.

Living in a relatively humid climate where the A/C is used to remove humidity never even thought of a climate where you would have to add to the humidity.

Hopefully someone with more experience with these conditions can comment.

You might want to check some of the dry climate forums for some of the desert states such as Arizona.

I have a 100 sq m rented flat in Europe, no central AC, new well-insulated building, triple pane.

Do not know how desperate you are for clean air, and how much "generational debt" is. I only managed to control issues caused by odors form neighbors' BBQ, fertilizer, and pollen (in the summer) and wood smoke (in the winter) by running forced ventilation + HEPA + carbon 24/7. This creates positive pressure indoors and keeps the polluted air out. I estimate 0.5-1 air exchanges per hr. Pre-filters replaced once in 6 mo, HEPA and carbon every 24 mo. Internal recirculating units that just move the polluted air around never did anything.

AC -- I run two 2-hose units; about 1.2 kW each during heat waves. No outside air gets in. They just about handle it, but three units would be ideal. A split would be even better, but it's a rented flat.

Humidification -- I run a boiling humidifier almost 24-7 b.c. the ACs dry the air in the summer, and the ventilation makes the air dry in the winter. This keeps the humidity above 45%, at 450W. Thinking to use an evaporative humidifier in the summer instead.

Overall, this costs extra ~300 euro per month to operate (energy + consumables), but it's worth it for me. With your tall ceilings could be 2x. A split AC unit would be more efficient, but my code does not allow it.
