Product Description

GeneralAire's 1099-20 evaporator pad, sometimes called a humidifier/water filter, performs an important role in the humidifier. The pad soaks up water as it passes through the humidifier, and then circulates humidity into the air. This keeps your home or business comfortable during the dry season. This pad is made of aluminum encased in a heavy wire frame, and is coated with a special absorbent material which evenly draws water across the pad, and increases the amount of humidity produced. While these pads work hard to provide clean and comfortable air, as time passes, pollutants and minerals build up on the pad and diminish performance. It’s important to note that the pad cannot be cleaned, and must be replaced at least once a year to ensure superior performance and air quality. Fits models 1099, 1099L, 1099LH, 1099R.

This component is also known as part number: 7047

This item is sometimes called a media filter, humidifier pad or water filter. The manufacturer is sometimes referred to as General Filters, General Air but is correctly spelled GeneralAire®.

Exactly what we needed by D Irvin (Kansas City MO US)

Even though our furnace isn’t brand new, we were able to find the appropriate evaporator pads for the attached humidifier. It’s the second time we’ve ordered replacements so we will always have the pads on hand for the yearly replacement. The ordering was simple and delivery very fast.

Jim by Jim LeMarbe (Milford MI US)

The fact that a person called me back because I ordered the wrong product for my humidifier Shows me what kind of company you are. Keep up the good work.

Evaporator Pad by wilbur M. Lee jr (Southfield MI US)

The first pad was damaged. The delivery service should have not left it based on the damage of the package. The replacement evaporator pad was ok. Your rating was a 4 stars instead of 5 stars because the first unit was damaged. It was no lower than 4 start because you excepted the responsibility of the damaged unit and sent a replacement unit.

Home Owner by dan cherewick (novi Mi US)

I have been using the wrong evaporator pad since I bought the house. This resulted in very low humidity in the house during the winter. Recently, an HVAC contractor inspected my system and informed me of the wrong pad issue. I recently replaced it with the 1099-20 pad and I am noticing an increased humidity level while heating. So far, so good. Thanks for every thing.

"General Aire 1099-20 Evaporator Pad by james jondrow (Canton Township MI US)

Very impressed with the speed of delivery. Pad works great.

Dec 16, 2015
Exactly as expected by Kathy Dymecki (Milford MI US) made it easy for me to find the pad I needed for my humidifier. I couldn't find any of the original paperwork, nor had I ever replaced the pad before. My order arrived promptly and it was pretty much a no-brainer to get the humidifier cleaned and ready for the winter season. I guess this was exactly as it should be, and isnt that a good thing when it happens?

Perfect Experience by Julie (Canton MI US)

After having our appliances inspected before the winter, we were told we needed a new humidifier pad. The company we go through is a little pricey for parts off the truck. I did a search and was so fortunate to find General Aire. It shipped quickly and it is exactly the part we needed. The website was easy to navigate and the price is great!

Satisfied Customer by D Moyes ( )

I purchased, via the company's web site, an evaporator pad and a small obsure clip for a humidifier. The pad I replaced was at least 15 years old and the clip had been lost during an attempt to clean the pad. Firstly, I expected difficulty finding replacement parts, either locally or online; however, once I found this company's web site, I easily found and ordred the parts, which were readily available. Secondly, my order was processed and delivered in a timely manner, as promised. And thirdly, it is apparent that someone at this company is working hard to satisfy cutomers. Thus, I won't wait another 15 years to order the next pad.

After talking to the General Filter Technician I was ready to go and get my unit running again . The General Filter people are very knowledgeable and courteous and not in a hurry to get you off the phone until you are made aware of all possibilities on how your equipment is supposed to work .

Mr. Locke by Nolen Locke (Belleville Mi US)

I purchased the parts for my daughter and son-in-law's furnace. They had purchased a pad at a big box store, one size fits all, but over time it shrank and was no longer covering the opening which allowed unhumidified air to bypass the water pad. Probably most of the air was bypassing the evaporator. I found this site on line and ordered the correct pads and they slid right in place. Delivery was good and on time as expected. It is working fine.
