What is the desired average indoor humidity level?

The human body is comfortable when relative humidity ranges between 20 and 60 percent. In your home, an average relative indoor humidity of 30 to 50 percent is appropriate when the outside temperature is 20°F or above. During cold weather, higher humidity ranges may cause structural damage because of condensation on windows and on the inside of exterior walls. As outdoor temperatures fall, condensation problems may develop inside, leading to mold and other complications.

Maintaining a proper average indoor humidity level helps you feel more comfortable and helps protect your home. Our IW25-4 in-wall/on-wall dehumidifier can help with this plus mold control.

Recommended average relative indoor humidity level by season:

Winter
20%+
(Indoor temperature
between 68 and 75 degrees)

Summer
No more than 60% average indoor humidity
(Indoor temperature
between 73 and 79 degrees)

"We recently began installing your dehumidifiers on our first rehab project and have been getting a lot of positive feedback on them. Dan asked me to reach out to our property manager at Arbor Lake to have her tell the story she told me last week in regards to her new dehumidifier so that we could share it with you and your team. Below you will find the story from out property manager Tia Ward at Arbor Lake.

Backstory: I develop bronchitis every winter and have bronchial spasms stemming from allergies that make it difficult to breathe. During my most recent doctors visit I was informed my breathing was at 67% which was an improvement from 58% the month prior. My daughter has asthma often uses an nebulizer to control breathing and reduce cough and wheezing especially when she develops a cold.

My dehumidifier was installed Feb 3 before noon and upon returning home after 6pm it was still running. That night I noticed I coughed far less. My dehumidifier ran continuously from Feb 3rd to Feb 6th (late evening). The entire time I was happy knowing that it was helping both me and my daughter to breathe better. I kept saying to myself, Thank you little machine, for helping us breathe better. Today is Feb 14 and I have to admit that I feel so much better and I cough far less than I once was. Prior to installing the dehumidifier I was coughing constantly just talking, laughing and/or eating. I can surely tell there has been a huge improvement. I haven't had my return office visit to my doctor yet but I’m looking forward to my testing. I smile every time I hear the machine come on (it isn’t loud at all). While the counter tops, appliances, and all the other upgrades look nice. I'm most thankful for the little machine that is helping us breathe better.

Thank You."

"We have purchased and installed about 11 of the IW25 permanent dehumidifiers, and they are performing very well. They have remedied our ongoing problem with high RH in certain apartments, and are the perfect solution. The fact that we can install them, set, and forget them is the true beauty of the product! Previously we had tried to manage the problem by supplying portable dehumidifiers, but always had trouble. Even with the best of intentions, the resident fails to empty the bucket, or turns the portable off because of noise, or some other reason. But the resident quickly forgets the permanent dehumidifier is even there. It is quieter, out of the way, and requires no effort or attention from the resident. It's been a great solution for us!"

"As a resident of the north east we experience many days of high humidity throughout the year. I searched the internet until I ran across Innovative Dehumidifier Systems. I called and spoke with the tech people and a sales representative and decided to purchase their IW-25-4 IN Wall unit it wasn't even on the market yet, it was still in development. I placed the order and within about 5 weeks it was sitting on my porch just as promised. It was very easy to install only took less than a half hour to have it up and running, its working great I'm very pleased with the unit and the folks at Dehumidifier Systems." -Paul B. Pennsylvania

"I am pleased to inform you that I have had a positive experience regarding all aspects of the dehumidifier; performance of the IW25 unit has surpassed my expectations with regard to ability to extract moisture in cool(er) ambient temperatures. I truly wish there were more US companies with the manufacturing attention to detail and level of customer care and concern that Innovative Dehumidifier has provided. I'll be spending my money with the Innovative Dehumidifier Company the next time I have the need.
Thanks again!" Regards, Travis M. Electrical Engineer
