Consumer question:

I have a Aprilaire 600m model and should I conect the water supply to the hot or cold line.

Aprilaires' response:

Consumer question:

Can I set my air cleaner to a mode in which it will only be active when the furnace (or air condition) is running? And what is the difference between the Constant Cleaning mode and the Allergies mode - is it that the Allergies mode shuts the air cleaner after 24 hours and then what?

Aprilaires' response:

Consumer question:

I didn't notice this until recently, but our Aprilaire 760 runs regardless of the furnace blower running, whereas our 550 model does not. Is that typical for the 760?

Aprilaires' response:

Consumer question:

My Aprilaire model 760 humidifier that has worked great for the last 11 years has a short that apparently cannot be repaired. So what would it cost to get a new one that will fit my furnace exactly like my 760 did. Also the cost of a new one, or can mine be sent in for repair.

Consumer question:

My 8463 Aprilaire Thermostat was installed with a new furnace and A.C. The thermostat was programmed to 5-2 by the installer. I want it to 5-1-1. The installer did not know how to do it and the companies techs are stumped. How can I change this thermostat from a 5-2 to a 5-1-1? Or can I? I would like the settings for Saturday and Sunday to be different.

Aprilaires' response:

Summer is almost here and with it we welcome the long-awaited warm weather but not the sticky, high levels of humidity that often come with it.  High humidity affects the quality of indoor air and can affect the health of you and your family in a variety of ways.

High humidity levels can cause mold, encourage dust mites which are a major cause of allergies, and cause a hot of problems in the home that can affect your physical health.  Visible signs of high humidity levels include condensation on windows, peeling wallpaper, damp patches on walls and ceilings, a musty smell and dampness.  But there are also numerous problems that go undetected because you can not see or smell them. 

A few of the most common health effects of too much moisture in the home include the following:

Dust mites:  At least 10 percent of the population suffers from a dust mite allergy.  Half of American homes have enough bedding with enough dust mite allergen to cause allergies.. Of these homes, 24 percent had levels that were five times greater than the threshold to cause allergic reactions.

To control dust mites, experts recommend regular cleaning to reduce dust, as well as encasing mattresses, box springs and pillows in allergy-free cases.  The more dust-free the home, the less likely it will be able to support significant populations of allergen0causing dust mites.  Some of the symptoms associated with it include sneezing, itchy, watery eyes, nasal stuffiness, runny nose, stuffy ears, respiratory problems, atopic dermatitis and asthma.

Bacteria: you can't see or feel bacteria but they live on countertops, table surfaces, carpet, pillows, mattresses and just about anywhere people are.  Bacteria also grow profusely when there is plenty of moisture present.

Formaldehyde: When humidity levels are high, products such as furniture, cabinets, building materials and even some latex paints then to release formaldehyde into the air at a faster rate.  Studies have suggested that people exposed to formaldehyde levels ranging from 50 to 100 parts per billion for long periods of time are more likely to experience asthma-related respiratory symptoms, such as coughing and wheezing.

If you suspect that the air in your home is too moist, be sure to vent the areas that create moisture, like the show or bathroom.  You may also consider a whole home dehumidifier like the Aprilaire Model 1710A, 1730A,1750A or the 1770A.  The Aprilaire dehumidifiers can work independently or in tandem with the heating and cooling systems to remove extra moisture from your home.  A system like this will allow homeowners to achieve the EPA recommended humidity levels in the house of 30-50 percent.

The air in American homes is increasingly contaminated and polluted, and now studies have linked poor indoor air quality to the dramatic rise in not only allergy and asthma symptoms, but also a variety of other health issues, including heart disease, stroke and blood clots.

Studies are emerging that prove poor indoor air quality can cause or contribute to a variety of symptoms and medical issues.  While individuals with pre-existing medical problems such as asthma, chronic obstructive pulmonary disease (COPD) and allergies are at most risk from poor indoor quality, the medical literature demonstrates that even those in a good state of health are negatively affected.

The latest study conducted by scientists from Denmark and Sweden, published in the American Journal of Respiratory and Critical Care Medicine, reveals that poor indoor air adversely affects the performance of blood vessels in humans leading to cardiovascular disease.  The study also found that indoor air filtration greatly reduced the amount of ultrafine, fine and coarse air particles in the homes tested, which was associated with an actual improvement in the microvascular function of the study participants.

In an effort to protect public health and combat airborne invaders, Aprilaire, a leading manufacturer of indoor air quality products, is urging consumers nationwide to consider whole-home air cleaners as part of a modern and integrated approach to managing their indoor environments. Homeowners can be sure that a whole-home air cleaner works to permanently trap the airborne contaminants that most affect health and aggravate allergy and asthma symptoms, moving clean and comfortable air throughout every room of the home, all while operating silently and out of sight.

While the medical community acknowledges the benefits of clean air in the home, consumers often find themselves disappointed with the options available at local home improvement centers where portable, do-it-yourself air cleaning units are sold.

“We know through research that most people buy portable air cleaners to help alleviate some sort of respiratory issue, this cannot be accomplished with one portable air cleaner for an entire home,” said Mike Rimrodt, marketing director for Aprilaire. “In fact, most homes require four or five portable units or more too clean the air throughout the entire home and still don’t do as good a job,” notes Rimrodt. “When comparing performance, installation and maintenance factors, and overall cost, a whole-home air cleaning solution is ideal for families who want to ensure healthy, clean air in every room and get the best value for their dollar.”

Whole-home air cleaners permanently trap the airborne contaminants that can aggravate health and allergy and asthma symptoms. In a recent standard industry test, the Aprilaire 5000 achieved 99 percent efficiency against airborne particles. The unit captures and kills virtually all contaminants including those that most affect personal health—viruses, bacteria, spores and allergens 24 hours a day, seven days a week, 365 days a year.

Aprilaire also offers homeowners a one-of-a-kind air cleaner control that allows them to actively clean the air in their entire home based on personal preference and event triggers. A simple-to-program thermostat features Event-Based ™ Air Cleaning:

• Constant Cleaning:  air cleaner is active for 24 hours a day seven days a week
• Automatic:  air cleaner will run a minimum of 30 minutes per hour
• Event Clean:  air cleaners will run for three hours continuously and then turn off
• Allergies:  air cleaner will run continuously for 24 hours and then turn off

Event-Based Air Cleaning also provides other conveniences such as indicators that air cleaning is taking place as well maintenance reminders.

Periodic Preventative Maintenance

• NOTE: Periodic inspection and preventive maintenance of your total heating system is important for efficient and safe operation. Your heating contractor should include humidifier service at the same time. All models are equipped with an in-line water strainer and orifice as shown below. These parts should be inspected and cleaned periodically to assure continued proper unit performance.

Recommended Annual Maintenance

• The water panel should be changed once a year, with a few exceptions.
  • The model 400 has a panel that should be changed twice a season
  • If extremely hard water is used in any Aprilaire humidifier, the panel should be changed more frequently than once a season. 
  • The water panel cannot be cleaned because it has a special coating that helps the water adhere to the panel while the air is passing through it.  Without the coating, more water will go down the drain and less will be converted into a vapor.
• Drain line
  • Detach the drain line from the drain spud at the bottom of the unit. 
  • Bend it at the various points to loosen calcium deposits which may have formed on the inside of the line, and flush it with pressurized water. 
  • You can also pour bleach through it prior to the water.  This will kill any micro-organisms that happen to be living in the drain line. 
  • The drain line can be replaced should it prove difficult to clean. 
• Feed tube
  • Detach the tube from the nozzle at the top of the unit, and unscrew the end of the solenoid valve at the other end of the feed tube. 
  • Run high pressure water through the tube and replace. 
  • When reconnecting the feed tube, remember to double wrench the connections to prevent leaking.
• Inside of unit
  • Look for any mineral deposits on the Scale Control Insert after removing the water panel, and get rid of them by wiping the insert with a damp towel or rag.  They should come right off. 
  • If there are deposits on the inside of the cover, or in the case of a 700, on the fan blade, it may be indicative of a larger problem known as entrainment.  ()
  • Do not remove granulated coating on the distribution tray – not an issue with the new ones. 
    • The granular coating is there to break up the surface tension of the water.  This allows water to flow evenly through all of the openings in the water distribution tray. 
    • The newer trays have a fabric along the bottom of the tray which does the same thing as the granular coating.  The difference is the customer doesn’t have to worry about scraping off the fabric.
• Hard or Soft Water
  • Aprilaire offers total flexibility in the installation of our humidifiers in that they will operate properly with either hard or soft water. Connecting to hard water may leave mineral deposits on the water panel that are scaly and hard in nature. Connecting to soft water may leave mineral deposits that are fluffier in nature. The bottom line is the water panel will typically last a full heating season using either type of water.  When extremely hard water is used in the humidifier, maintenance should be performed approximately every six months.
