How do I change my replacement humidifier filter?
It is time to change the pad on my model 400 which I purchased in November 2009. I followed the instructions on the replacement pad box and from the owner’s manual on your web site. Both instruct in step 4 to tip the Water Panel evaporation assembly forward and lift it out of the humidifier. I tried to do this but the assembly appears to be attached at the top on both sides to the housing and I can not see or figure out how you remove it to get the assembly to tip forward.
Would you please instruct me on how to do so?
Aprilaires' response:
The internal components of the model 400 will require that they be removed from the humidifier in order to replace the water panel successfully. To remove the internal case from the base of the humidifier, you will need to pull it out from the top where the distribution tray is located. When pulling the internal case from the top you will need to tilt it towards you to remove the components. Once the internal parts are removed the water panel can be replaced at that time by removing the tray on top. After removing the distribution tray from the "U" shaped frame, pull out the used water panel and place the new water panel in the "U" shaped holder. We have also included the owners manual that references the proper process for replacing the water panel for the model 400 humidifier.
Is my replacement humidifier filter working?
I recently installed the humidifer and it worked fine for a few days. Now it is leaking water out the bottom and not through the drain hole. Could the filter be defective?
Aprilaires' response:
Thank you for contacting Aprilaire. Humidifiers can leak for several common reasons,
1) Is the unit level?
2) Inspect the feed tube for cracks.
3) Is the water panel in upside down?
4) Is the scale control insert cracked?
5) Does the drain line plugged or restricted?
6) Erosion of the water panel do to reverse osmosis (RO) or deionized (DI) water.
7) Heat registers in the house that are closed?
Closing heat registers can cause high pressure in your ducts which can blow water off of the water panel. If the static pressure in the duct is more than .4" of W.C. water will be sprayed off of the water panel.
I hope this helps. If you still can't stop the unit from leaking you will need to contact your local HVAC contractor or you can call our technical support department for more trouble shooting assistance. You can reach us at 1-800-334-6011 Monday - Friday from 7:00 AM to 5:00 PM central time.

Is there a air dehumidifier filter upgrade?
Is it possible to upgrade the efficiency of the pre-filter from the current MERV-8?
Aprilaires' Response:
Thank you for contacting us with regards to our Model 1750 Dehumidifier. We do not offer a high-efficiency filter for this model other than the supplied MERV 8. However, if this unit were attached to your HVAC system and its intake positioned downstream of your HVAC filter, that could potentially have a higher efficiency than MERV 8. In that situation, the internal filter would not be needed as all air it uses would be pulled through your HVAC filter. For example, our Aprilaire whole-home air cleaners begin at MERV 10 and go higher from there. The two could work together to give the 1750 cleaner air than the dehumidifier could create on its own.
We appreciate the opportunity to be of assistance.
Have a Happy Spring with Aprilaire
Do you remember last spring when all the snow was finally melted and it got warm enough
outside to go without a jacket? Do you also remember that it wasn't warm enough to turn on the air conditioning, but you still felt uncomfortable? This happens every spring due to the high levels of relative humidity (RH). The phrase "it's not the heat, it's the humidity" is all too true. High RH levels can make it feel like it's 5 to 10 degrees warmer than it actually is. One way to combat this is to turn on your air conditioner, as moisture removal is a natural byproduct of air conditioning. But in order to remove the excess moisture, you need to cool the air to a level that makes you too cold.
Aprilaire to the rescue
A whole-house dehumidifier from Aprilaire works in conjunction with your home’s HVAC system to remove excess moisture from every room of your home. Unlike air conditioning that is designed primarily to cool your home, Aprilaire removes moisture when AC is not required, efficiently removing moisture and providing the comfort you deserve. Maintenance is a breeze with Aprilaire as well. Unlike portable dehumidifiers that require you to empty and clean a tank on a daily basis, Aprilaire dehumidifiers only require an annual filter cleaning. Hassle free convenience and comfort; that's what Aprilaire is all about.
Contact your Aprilaire dealer and schedule the installation of your whole-house dehumidifier today and avoid all the discomforts you felt last year. Your family will thank you for it.

I want to upgrade!!
I have a Model 5000 filter. I'd like to get an upgrade kit, but I am not sure whether there is one that would fit. I am confused between the Model 2400 and 5000 and the media for each. Are these two different models with interchangeable parts?
Aprilaires' response:
There is no upgrade at this time for the model 5000 electronic air cleaner. Because of the electronics involved, we have not yet come up with an upgrade for this unit.
The size of the 5000 is the same as the size for the 2400. Although, the 2400 is not electronic. Also the filter used in the 2400, even though the same size, is not recommended for use in the 5000, just as the filter for the 5000 is not recommended for use in the 2400. The 501 filter for the 5000 has metalic stripping on the pleats of the filter. These are necessary for the correct operation of the 5000. If you put a 401 filter into the 5000, sure it would catch dust, but you would loose all the electronic capabilities that you purchased the 5000 for in the first place.
Smoking and air cleaners
I won't do that. Even our Model 5000, the best whole house particulate removal product, will not deter the harmful affects of 2nd hand smoke. It WILL help clean your air of all kinds of nasty stuff; virus-sized particles, allergens and other contaminants.
It's best just to properly ventilate, or maybe just don't smoke in the house. Go outside with the other 2nd class citizens!
Right side up, right side down...I'm all turned about.
Can the inlet and outlet of the 2210 be reversed? Because of the pitch
of my roof I can only install the unit in one direction.
Aprilaires' response:
The 2210 can be installed with the inlet and outlet side reversed. The important point is that the filter media needs to be installed with the airflow arrow in the proper orientation of the air flow of your HVAC system.
700a, 700m 700...Aprilaire Power Humidifiers
We are a contractor operating in Toronto, Ontario Canada. We recently
installed an Aprilaire 700 Humidifier for a customer. Our customer prefers
the model model 700A. Can his 700M !!! be upgraded to 700A, without having
to replace the whole unit?
Aprilaires' Repsonse:
The 700M may be converted to the 700A by replacing the manual humidistat (part #4655) with our automatic digital humidifier control (part #58). The only difference between the 700M and 700A is the control. Since they are one in the same it will also use the same Aprilaire water panel number 35, also refered to as a replacement humidifier filter.

* More than 31 million Americans have been diagnosed with asthma, about 1/3 are children under 18.
* About 40,000 dust mites, a common household allergen, can live in one ounce of dust.
* An estimated 10-15% of the entire population may be allergic to cat or dog dander.

Different by the same?
I am looking at replacing my model #760 Aprilaire Humidifier with a model #700 Aprlaire Humidifier. Are the cutout openings the same size? I would like to remove and replace with out any plenium modification.
Aprilaires' response:
The 700 Aprilaire Humidifier and the 760 Aprilaire Humidifier are very similar and can be swapped with minimal modification to the plenum. Here are the differences:
760-14 7/8"W x 14 3/16"H
700-14 3/4"W x 14 5/16"H
Don't worry if you have left over humidifier filters (water panels) as both humidifiers use the model 35 water panel.
Please let us know if you have further questions.
Red light, green light.....amber light?
A green light is lit. The green light is next to it is the text change filter. I checked online for the manual, there were only references for 600m and 600a. Please advise if this green light means I need to change the filter.
Aprilaire's response:
The green light simply means the humidifier is on and running. The "Change Water Panel" light is amber in color. The "Call Dealer" light is red. Similar to a stop light.
Please feel free to ask about any other issues or observations you see. We would be happy to help.
Is my drainless humidifier working?
This unit was installed and worked great for two years. Then I turned it off in the summer and forgot to turn it back on for the last two years. Now, I changed the filter and cleaned everything out. However, it doesn't seem to work. The humidity in my house is 10.
I hear the water turn on for a few minutes at the beginning of the heat cycle. Then it turns off. When I look at the filter, it is only wet at the bottom 1 inch. The rest is dry. The water seems to go into the first float chamber, but doesn't go into the second chamber. I don't see what is preventing the water from moving over.
I had the technician, who installed it, come and look at it. He suggested changing the filter and isn't sure what is wrong. He hasn't been doing this humidifiers for a while. He thought that it might be the water level sensor assembly. However, no one seems to have this part in stock. I will have to order it and get it installed. Then, I might find out that is not what is wrong, and I will have paid more money to have the wrong thing fixed. I already spent $85 for the technician and $45 for the filters. I really want to get it fixed. Can you make some recommendations?
Aprilaires' Response:
Thank you for contacting us with regards to your model 400 Humidifier. Based on the information you provided, the humidifier is working properly. The water should fill from the top, trickle down across the water panel. Verify that you are using a Genuine Aprilaire Stock #45 Water Panel. The water will only raise the float in the right-hand chamber. The left float is an emergency overflow. Water should not fill that chamber unless the first fails to shut off the water. The fact that the water does shut off indicates that the sensor is working properly. The water panel should then wick water up from the reservoir and it will evaporate as it rises.
Water shouldn't rise very far before it evaporates, but most of the water will rise up through the center of the pad, as opposed to the outer layer of material. As long as the humidifier refills at the beginning of, or during, each heat cycle, the humidifier is working. For a test of how well it's working, please do an Evaporative Test. This can be done using a measuring container and a timer.
The evaporative rate of the Model 400 is based entirely on the temperature of the heated air and the amount of run time of your furnace. The performance values are based on 120°F air and 50% run time. This should give 0.70 gal/hr.
It's not clear from the information you provided how long the humidifier has been running with your home at 10% RH. Did it start at 10% and it hasn't changed, or was it higher and has since fallen, or was it lower and has since risen? Humidity can take a while to change, so we would look at the trend of the humidity over time, if it's going up, down, or staying the same. At this time, it doesn't make sense to replace the water level sensor from a troubleshooting standpoint.
Aprilaire Dehumidifies Your Entire Home
Springtime is just around the corner. Soon all of us will be able to turn off the furnace, open the windows, and let some fresh air in the house. Or will we? The outdoor temperature seems inviting, but how's that humidity? When you open those windows, do you also open up the potential to bring in lots of moisture that can make you uncomfortable as well as damage your home? You could keep the windows closed and turn on the air conditioner in an effort to dry out the air. But now you’re too cold...and frustrated.

Upon Further Review - IS Online retailer Cleartheairinc.com misleading the consumer? Maybe NOT!
They assure me their intentions were never to mislead. I guess I'll never know that for 100% sure, but I'm ready to give them the benefit of the doubt. After reading of my concerns they immediately took action to modify the language on their site and clarify what the consumer is buying.
I applaud their quick response and willingness to set things right.
Good luck, and if you're happy purchasing filters for Aprilaire Air Cleaners that are not made by Aprilaire, Cleartheairinc.com seems like a fair place to trade.

From Friday......
The site tries to cleverly describe the filter as "Clear the Air's Aprilaire Spacegard replacement filter". They probably do this so that they could argue that legally they are calling it a "Clear the Air" brand and therefore NOT misleading the consumer into thinking they are buying an Aprilaire brand.
You decide. Take a look. Would you think you were buying a filter made by Aprilaire or SpaceGard on this page?
They do this with other brands as well.
Sleazy.
If you have an Aprilaire or SpaceGard air purifier / air cleaner and you typically replace the flters yourself, ask an Aprilaire dealer in your area. Often they will sell them to you off the shelf. And they'll be the real deal!
UNLIKE CLEARTHEAIRINC.COM, I'LL BE VERY STRAIGHT FORWARD WITH YOU. Take a look at the estore on Aprilaire.com , just so you get an idea of what the real thing looks like.
Sure, you can buy them there. But that's not the point. I could care less if you buy from our estore. We're the manufacturer! We get the sale of Aprilaire product regardless of where you buy it. Just go there to see the pictures. Then you'll know what the real deal looks like. Then. if you want to shop around, you can get them cheaper on other websites or from your local dealer.
And at least you'll know what you're getting for your dollar.
Keep Indoor Air Healthy In the Winter
The EPA says indoor air can often be many times more polluted then outdoor air. Further they say we spend as much as 90% of our time indoors. In the winter when it's cold outside the percentage is probably even higher so it's important to understand what you can do to make sure your homes indoor air is clean.
There are some real basic things that can be done including use non toxic cleaners, dust often, use fans when cooking, wash your bed sheets in hot water, if you have an attached garage pull your car out right after you start it, don't smoke indoors, and the list goes on.
Despite doing the aforementioned items you're still going to end up with particulate and pollution in your homes air. Due to the fact that in the winter there is very little fresh air getting into your home that pollution can build up and cause everything from cold symptoms, sore throats, stuffed up noses, allergy symptoms to much more serious long term effects like asthma and other long term respiratory health problems.
That is why it is important to have a whole home air cleaner to remove particulate in your homes air before you breathe it. Aprilaire offers 3 different levels of air cleaning with different efficiency ratings and control options. Control is a very important part of any air cleaner; most air cleaners only run based on temperature, which doesn't make much sense...you need to clean the air when your air is dirty and that has nothing to do with when you need to change your temperature. Look for more on the importance of controlling your air cleaner from me in future blogs.
H1N1 and Air Cleaning
Trapping Flu Virus with Air Cleaners
The real answer is IT CAN HELP! Our Aprilaire Model 5000 Electronic Air Cleaner DOES trap airborne particles down to 1 micron in size; well within the range of the size of flu viruses. Here's how:
If a virus attaches itself to a piece of airborne dust, and when your system blower operates, if that dust is blown through your return air ducts to the air cleaner filter, the Model 5000 will permanently trap 98% of those particles and they will not re-enter your living space.
In that way, the air cleaner helps control and reduce the spread of the virus. A virus that someone leaves on a hard surface may never be airborne so the Aprilaire air cleaner cannot help that---- NO air cleaner can!
Be sure you take all the precautions that the pros tell you about the spread of the flu.
