High Humidity in the Condo Unit

Hi,

I was hoping to get some advice.

Is it normal for humidity to be really high inside a condo unit if its humid outside?

For example, if humidity outside is 77%, my condo unit is at 77 RH%.

I feel my condo units humidity/RH% is fairly high in comparison to the norm. I am on the 15th floor though; I'm not sure if that would have an impact.

Is there any tips or things I can do?

Thank you.

You can purchase a dehumidifier and just run that.

Are you keeping the windows close? Do you not have a/c in your condo?

Depends on your condo. Old Condos yes.

They don't have fancier ERV systems and aren't very well sealed. Their old air exchange systems just passed thru some fibre glass filters and called it a day. So it's going to be nice and humid just like the outside.

Bumping this, new condo dweller here.

I have the same issue and my unit is not even a year old, it does have a ERV and it feels like the fan coil unit barely does anything on high fan power.

Is buying a dehumidifier the only solution? I'm looking at the cheapest units and they're all $150....I'm tired of buying little units for everything, air cleaner, tower fan, humidier and now dehumidifier.... will I need a heater for winter too??

you shouldn't need a dehumidifier.

If you have kitchen/bathroom exhaust fans, use them whenever showering/cooking.

Reduce the fan-coil fan speed if you can from the wall control/thermostat -> lower speeds are better for dehumidifying, the air stays in contact with the cold coil for longer. You should also set the fan to auto, not on, to prevent condensed moisture from re-evaporating from the coil when cooling setting is reached.

If problems persist, get condo management involved.

Why not run AC?
How long do you leave windows open for?

I run the AC but it doesn't cut the humidity enough. Windows are always closed.

I'm going to take a closer look at the fan coil controls, it's complete garbage and WiFi features were discontinued despite being released just last year.

Thanks for the tips!
