Customer Q & A
Q1: Which way is the air flow?
There are indicator arrows on each filter to show you how to install it, but if you cannot read them for any reason, remember, the side that has the metal mesh, is where air exits. Hope that helps!
Q2: Should I ryn the fan continuously to get the most filtration? Any idea the impact on the electric bill? Thanks
This is a tough question. There's a bit of a balancing act between electric usage and air filtration. Running the fan continuously would likely run you about $20 more per month. That's $250 a year. This is just an estimate since I don't know the blower motor size or draw and don't know what electric costs per kWh where you are located. The flipside of this is that the filtration is only helping when the blower is actually on. My first thought is no, don't run it continuously. I don't know if they extra use/wear and tear on the blower motor and bearings plus the actual extra energy usage is worth it. I would likely suggest you try it one month and see how it works. Check your electric bill to determine what day your billing cycle starts on, then turn on continuous. You'll have a very good idea of the extra cost, and it shouldn't be too much more expensive. That is bit of a roll of the dice since electric rates can vary from over 20 cents per kWh to less than 10. I would also say. The other potential downside is depending on where you are located, you may not want the blower moving around air that isn't being warmed. The more I type, the more I feel like I'm talking you and myself out of this! In any event, those are a few things to consider, and again, trying it for a month would give you a good idea as to whether you notice a difference in air quality and what kind of impact it will have on the power bill. Hope that helps!
Q3: We currently use a Carrier electrostatic air cleaner. The two side-by-side collectors total 20"x25" by 5" thick. Would it be feasible just to replace the collectors with one 20'x25" Filtrete 1550 air filter, or do we need to replace the entire unit?
You could try the Filtrete filters, and they'll certainly do better than nothing. Though I'm not sure of the exact model you're describing, the Filtrete should work as a replacement. The part I'm unsure about is if your model sends a charge through the filters, and that raises two questions for me. I'm unsure if when used with their handy dandy electrocution technology, would they present any type of hazard? I would guess not but I do not know that for sure. Secondly, does that unit product any ozone or does Carrier publish that. I would assume it's below CARB standards, but again, I'm not sure. Long term, if you don't plan on continuing to purchase their filters, it might be easier for you to just remove the unit and install a housing that would fit a 4" filter, like the Filtrete. They allow adequate airflow, and like all Filtrete filters, they are electrostatic by nature, so with that slight charge, they do a good job of drawing particles in and holding them without any additional filtration features. Sorry for the delay and hope that helps!
