Hi,

this is my first year in Canada and I realized that humidity in the basement in the summer can get very high 75 - 80% or very low in spring 20-30%.
I now begin to see the effects, the laminated flooring in the basement has begun to buckle and therefore I am busy hunting for a good dehumidifier.

I have spent three evenings on the internet and I am discouraged because there is absolutely nothing on the market that guarantees a minimum level of quality. Basically, you buy something which for sure won't last more than 2-3 years in the best case, this is unbelievable.

However, if the market doesn't offer anything good, you have no choice.

My basement is divided in three rooms:

1 bathroom
1 guest room
1 family room

the damp problem is in the family room because there are no windows, the other rooms are OK.
The area of the family room is roughly 500 sf and according to the various tables I would need a small size dehumidifier.
However, I understand that there is a ratio which probably would allow me to optimize the energy consumption vs the time it takes to absorb the humidity, so I may go for something bigger, but I am still confused because according to the tables 500sf of a very damp basement would require a dehumidifier of 15 pints/day, which is very small.
If you go in any shop, your see tables showing that below 50 pints/day is not suitable for basements, therefore my doubts.:eek:

Can you help me to do the right choice size wise?

Thank you
Alex

I would go with the largest one I could afford. They all have humidity setting so, you can set it where you want.

Hi,

OK I bought a dehumidifier of 45 pints which is more than necessary, in fact, at lowest speed fan in 8h brought the humidity from 82% to 45%, which is good.

Now, I have some questions:

1) While the dehumidifier is ON, all windows stay closed, but obviously you need to open them sometime to let fresh air in, but an alternative could be to leave the air exchanger on, or does it have a negative role on the room while dehumidifying?

2) how long will it take for the buckled laminating floor to re-gain its original status?

Thank you and any additional suggestion is very welcomed! :thumbsup:

I enjoy when I can open the windows, also. By opening them you will defeat the purpose of the dehumidifier. As for the buckleing, it depends on what kind of material the core is made of. More than likely if it is not a high end laminate it won't shrink back much. I really don't know. You will have to wait and see. Good luck.
