Electric Furnace Filter is broken - what are my options?


You can turn off the breaker that controls the EAC. Press in the grounding button. Open up the box on top to expose the internal wiring. If you see a broken or loose electrical connection you can repair it. If not its time to pull the main cells and throw in a regular air filter with a brick to keep it in place or go for a 4 - 5 " wide filter.

Ozone is only a concern if you grossly over size the EAC.
With the exception of just few installations, all of the EAC I have seen are properly installed.

You can shop the internet and find repair parts super cheap if you need to repair the EAC

EAC are what are considered life long equipment investment. Our local EAC repair facility gets way less than 500 bucks to repair a unit.

You will have up keep on the EAC just as any piece of home comfort equipment, but the market is priced so that in most cases you can repair the EAC provided you aren't dealing with gougers.

In full defiance of the HVAC gods of today, I rant with another beer in my hand.

That old school technology has given somebody some of the highest air filtration possible for their air stream without increasing the heating bills for at least 20 years..
Measure the difference in the temp rise of a furnace with an EAC compared to a 4 - 5 " pleated filter. Measure the difference again when the 4-5 " pleated filter is dirty if half way through the year. Add that loss of furnace efficiency and heat related parts wear to the cost of those filters over 20 years and I'm not sure our new filter techology is an improvement. It is easier on the furnace tech's who don't have the patience to deal with an EAC, who can just off load the filter cleaning onto the customers & makes the stock holders of filter production companies happy but I'm not sure it is a real quality of life improvement or as cost effective as the old school.
You must REALLY like them. I took a course from Honeywell on them and the instructor showed us a bell curve describing the loss of efficiency/effectiveness. Day 1 and clean = 95% effective. Day 7 and the cells and ionizing wires have white ash/schmutz on them and the efficiency drops like a stone in a pond. Add to the fact that less than 5% of the owners know how or properly clean them and they don't work well at all. They give off ozone which smells like smog and we stopped selling them for all of the above reasons.

ALL EAC'S PRODUCE OZONE.
Here is the EPA's official take on ozone in the home and the use of EAC's

"
Ozone generators that are sold as air cleaners intentionally produce the gas ozone. Often the vendors of ozone generators make statements and distribute material that lead the public to believe that these devices are always safe and effective in controlling indoor air pollution. For almost a century, health professionals have refuted these claims (Sawyer, et. al 1913; Salls, 1927; Boeniger, 1995; American Lung Association, 1997; Al-Ahmady, 1997). The purpose of this document is to provide accurate information regarding the use of ozone-generating devices in indoor occupied spaces. This information is based on the most credible scientific evidence currently available.
Some vendors suggest that these devices have been approved by the federal government for use in occupied spaces. To the contrary, NO agency of the federal government has approved these devices for use in occupied spaces. Because of these claims, and because ozone can cause health problems at high concentrations, several federal government agencies have worked in consultation with the U.S. Environmental Protection Agency to produce this public information document.

What is Ozone?
Ozone is a molecule composed of three atoms of oxygen. Two atoms of oxygen form the basic oxygen molecule--the oxygen we breathe that is essential to life. The third oxygen atom can detach from the ozone molecule, and re-attach to molecules of other substances, thereby altering their chemical composition. It is this ability to react with other substances that forms the basis of manufacturers’ claims.
Top of page
How is Ozone Harmful?
The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs (see - "Ozone and Your Health" - www.epa.gov/airnow/brochure.html). Relatively low amounts can cause chest pain, coughing, shortness of breath, and, throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. People vary widely in their susceptibility to ozone. Healthy people, as well as those with respiratory difficulty, can experience breathing problems when exposed to ozone. Exercise during exposure to ozone causes a greater amount of ozone to be inhaled, and increases the risk of harmful respiratory effects. Recovery from the harmful effects can occur following short-term exposure to low levels of ozone, but health effects may become more damaging and recovery less certain at higher levels or from longer exposures (US EPA, 1996a, 1996b).
EPA's Final Non-attainment Designations for 8-Hour Ozone
On April 15, 2004 EPA designated as "non-attainment" areas throughout the country that exceeded the health-based standards for 8-hour ozone. The designations process plays an important role in letting the public know whether air quality in a given area is healthy. Once designations take effect, they also become an important component of state, tribal and local governments' efforts to control ground-level ozone. www.epa.gov/ozonedesignations/

Manufacturers and vendors of ozone devices often use misleading terms to describe ozone. Terms such as "energized oxygen" or "pure air" suggest that ozone is a healthy kind of oxygen. Ozone is a toxic gas with vastly different chemical and toxicological properties from oxygen. Several federal agencies have established health standards or recommendations to limit human exposure to ozone.

Use all the stilted reports you want.

properly sized EAC don't produce excessive ozone ....simple as that.

I have used Electro air for years , mostly the SST-14. I can smell ozone as well as the next guy and i never smelled any ozone on any of my installs.
Everybody should have an ozone meter s

Does this local repair faculty send soneone out to diagnose the EAC. or does the EAC get sent to them?

I'm 200 and some odd bucks (would have to look in my book to know the exact) to come out and diagnose and replace 1 wire.

I don't think the general population educated to at least a high school diploma, See's the EPA as an organization that would publish "stilted " reports.....

EAC's unless you are getting them fixed by an independant guy who does not charge $100-150/hr are VERY expensive to fix. We have a Video refit place in Wpg who fixes TVs but by the time you pay a Pro to disconnect and reconnect and drive it there and back it and do the repairs it will be $500-600 or more so VERY few people want to go that route. Some people cannot smell ozone and others are incredibly sensitive to it. We tried those carbon inserts back in the 80's but they only last a month. An EAC is a glorified bug zapper. The ozone gets produced by the arcing of mr bug or dust particle as it passes the ionizing wire and cells. Has nothing to do with the sizing as 90 % or more of the units we sold were 16x25 and a very few larger 20x25s. I am not saying don't repair it I just don't think it is worthwhile. Back in the old school days that was the best filtration system we had but now with Merv 16 filters and UV lights and ECM motors we can do a MUCH better job.

Electric Furnace Filter is broken - what are my options?


I decided to give it another shot this morning but same scenario - I can get it to stay on for only 10-15 mins before it shuts itself off. I'm beginning to think its a power or wiring issue.

If I decide to remove the cells and replace them with a 5" pleated filter, are there any drawbacks to this system compared to a working EAC? Is this the sort of filter I'm looking for http://www.homedepot.ca/product/2-pa...-m8-2pk/983869

those will work and look like a merv 10 and actually that is a VERY good price as you are buying 2. I sell them for $40 and up each. you need to take very accurate measurements and it is possible to crunch/squash them a bit to fit if necessary. you should check the temp rise thru the furnace with them as they can be a bit restrictive in some applications. if you can find a merv 7 or 8 that may be better. stick a metal cooking thermometer 1-2 feet downstream from the hot air plenum and subtract the house or return temp and compare it to the rating info sticker inside the furnace ie: 35-65 degF allowable temp rise.

The ozone level can be reduced with a quick modification of the board and making sure that the unit is only energized when the fan is operating.
Yuri is right that everyone has a different degree of sensitivity to ozone and so the EAC is not right for everyone. In my situation I am only dealing with EAC's that have already been installed and lived with so I only need to maintain, repair or disconnect them according to a customers varied needs.
In all honesty, my only customers that notice a difference between an EAC and the allergy filters are ones that have serious sensitivities to dust. If they don't have a medical sensitivity they often do just fine with a cheap $3.00 1" filter.
We can all find studys that will state just about anything but at this point in time I put most of my trust in my customers experiences. This goes for EAC, comfort levels of equipment, efficiency according to heating bills, etc

I'm not sure I understand this. Will adding a filter reduce the effectiveness or efficiency of my furnace?

Also, should I bother with prefilters if I get a pleated filter for the cabinet? The prefilters I have now are very thin...almost like grease traps for kitchen stove ranges.
