    Question

    Since I am getting my first heat pump installed next week, I decided that it would be a good idea to get a better filter system installed as well. The sales guy talked me into the Airscreen 1000 (after I groaned at the price of the Honeywell F300 Electronic Cleaner that they want 650 for). They want 299 for the Cimatec Airscreen 1000 and he told me it was a great product for the price.

    I asked about the media filters instead but he really discouraged me from those products (they offer the Honeywell F200 or F150). He said the replacement filters for those media filters are very costly and need to be replaced every 3-4 months whereas the Airscreen filters are very reasonably-priced (even though they also have to be replaced at least as often).

    I can't find much research out there about these filter systems and the pros and cons so I'm hoping I can get some advice out there. Will I be okay with the Airscreen 1000? I'm hoping so!

    thanks
    Monica

    Did you go to some place like

    http://www.aniline.com/products/Cimatec/as1000.html

    Looks like MERV 7. I just had a Aprilair 2400 put in, I think its a MERV8 or MERV10, but......I got it to kept my system clean, not to make my air pure. I'm more worried about the static load on my system that getting a super cleaner.


    The only work I got done at the time was the filter, so for the money, I had the worse scenerio (new duct work ect). If you just got a new system, that should have been a great time to get the best they had to offer. Ask your service company how much if you had it installed at a later date.

    I wonder what size filter, CFM and face velocity the .18 in wc airflow resistance is at? It looks like it is only 1" thick and designed to slide into a standard filter rack. You better be ready and willing to clean that thing more than once a month.

    I wouldn't recommend something like that to one of my cystomers. Without exeption, every product like that I have seen over the years was to restrictive to airflow. Usually the durability of the product leaves a lot to be desited also.

    Ask for an Aprilaire or other extended media air cleaner that you only have to change the media in every year or so. In most cases, the questionable benefits of an electronic air cleaner don't come anywhere close to being worth the extra cost and maintenance.

    I have yet to see an electronic air cleaner that keeps the equipment as clean as a good quality extended media filter. Most of the units I see with electronic air cleaners are no cleaner inside than if cheep disposable filters were used. The reason for that is electronic air cleaners much touted efficiency drops off VERY quickly as they get dirty. Once the cells have a coat of dust on them, they do very little, and almost nobody cleans them often enough to keep them efficient.
    If more government is the answer, then it's a really stupid question.

    Keep it as simple as possible ...

    deep Media Filter with ~ Merv 7 rating ought to be sufficient

    Also ask them about their experience with repairing UVs. When I asked for the aprilaire 2400 (non UV), the service guy tried to talk me into aprilaire 5000 - I asked him, do they break alot, yes. Do you get complaints on ozone smell, yes.

    I wanted a passive system that left me alone. Until your post I had never heard of Airscreen 1000. I had kept my research down to airbear, aprilair and honeywell. I went with Aprilaire because of a spring rebate, but I could have easily went with the other two.

    Do a google, and you'll get many hits, or even search here. Try just "filter"

    ooops should have said electronic not UV (though that is out there too).

    I read the spec again, it sounds more and more like the words that when with an air cleaner consumer reports shot down, where the electronic "effect" cleaned the air - what was that expensive piece of worthlessness called - air breeze?? - But at least what your going after has media.

    The airscreen 1000 is very much like the dynamic aircleaner. A 24v electronic with a changeable media in the middle. They have poor reliability on circuit boards and a high pressure drop. Anything mechanical is better. An airbear, april air 2200 or 2400, whatever, just get merv 7 or 8 and you will be happy and better off. Most extended pleat mechanical filters will last in most homes for a year.

    Another thing for you to considder.

    In my opinion, super duper high end filters in the equipment do little to actually improve indoor air quality. A good filter system will keep your equipment clean, wich will help keep you from having IAQ problems due to things growing in the HVAC equipment.

    Bottom line is that the air filter can't remove what never gets to it.
    The overwealming majority of dust and other polutants in your home will never reach the air filter in your HVAC system.
    They settle out of the air onto your furnashings, floors and walls well before they have a chance to get pulled through the air filter, even if the blower is on 24/7.

    If you want to make real improvements to indoor air quality in your home, the ductwork needs to be properly sealed, and sources of uncontrolled infiltration and/or exfiltration in the home need to be found and delt with.

    Hmm pressure drop

    The Airscreen 1000 literature states that it has a Pressure Drop of .15 in w.c. @ 300 fpm. The Honeywell Media air cleaners F200 and F150 have a slightly higher pressure drop of .18.

    If pressure drop is crucial, why shouldn't I just go with the Airscreen product?

    Surface area.

    The f159, 200, won't become restrictive as quickly.

    That .15 or .18 in wc @ 300 fpm does not reflect what will actually be going on in a real installation. Depending on the size system you have, you would need a filter setup with the airflow split between 2 or 3 of those Airscreen 1000 filters to get a face velocity of 300 fpm. In a typical installation with one filter located in a rack on the return end of the furnace, a filter like that is likely to produce a pressure drop >.3 in wc when it is clean and new. Since there is not much surface area to them, they get very restrictive very fast as they get dirty.

    Pressure drops through extended media filters are generally listed based on the total CFM passing through the filter. Listing pressure drop at certain CFM levels is much more realistic for compairing performance in actual installations. The huge surface area of media air cleaners also tends to cause the pressure drop to rise very slowly as the media gets dirty.

    You may want to look at going with an Aprilaire 2200 or 2400. They have lower pressure drops across the board than the Honeywell media filters.

    The contractor that I am getting my Trane heat pump through did not offer the Aprilair products so it may not be an option for me unfortunately.

    What's the price point on those Aprilaire products anyway??? Significantly more than the honeywell media air cleaners?

    I don't know about price point, but the dealer should be able to get the April Air from his supplier..

    I have the honeywell F200, and I am happy with it.

    Both filters are not that expensive.. Can get them from a hardware/home center store.
