Can anyone tell me what the CADR is on this unit? They claim good for 3500 sq ft home, but at what rate? That does not sound right, efficient for 3500

Small units like this are never CADR-rated because they don't have enough CFM. CADR is generally for big HEPA units that do their purification via forced-air-flow. These smaller (ozone/UV units) generally do their purification via said UV, ozone, or PHO cells, and the small HEPA filters on some of them are just to keep the air running through it clean.

The air exchange for a 3500 sq. ft. area is 5 times per hour. In an area 1/2 that size (1750 sq. feet), the exchange rate is 10 times per hour.

I don't know about 3500 feet but my basement is 2000+ sq feet and I have to use it on low otherwise I get that metal smell. It's Definately powerful .

I have a 1310 sq ft condo will this be more effective than your 3.5 ton unit. I uill be replacing an existing unit from the 70, s

35%Rh seems to be okay. For best efficiency run unit on 240vac. Locate the humidistat in the return air duct not on an interior wall. Do not use filtered water, especially reverse osmosis. Hardness of local water will effect overall efficiency. Locate the Aprilaire unit as close to the air conditioning unit as possible. Be sure to heavily insulate the steam line. Locate the steam tube on the down side air flow of the AC evaporator coils (if this is an AC unit) and as close to the down draft side of the burners as possible. You do not want the steam to condense on any obstruction in the air duct but close enough to the burners so that the steam is completly absorbed in the air stream. 35%Rh seems to be okay.

The unit us rated for 350 sq feet. I think that is about right if the home has normal insulation. And, on days that are 105F, any a/c unit is going to perform less than perfectly, yet this brand is top quality and will cool the room even in that climate. Thus, the smaller the room, the better a window unit will perform. Fortunately for you, you bought the best brand there is. Just an FYI regarding this specific unit...It was at my friends home freshly out of the box when we first we re able to test it out. Over the past few days when the temps have been in excess of 100F, he noticed that this Frigidaire produced clouds of condensation coming out of the vent because the unit cools the air so effectively, it actually condenses the moisture / humidity in the air near the vent as the super cold air flows outward. Now that is a fine a/c unit, in my opinion. I've never seen anything except a GM car air conditioner do that before.

Hi Matthew, Happy to help. This unit covers approximately 4000 sq ft. of space depending on the existing air quality of the space. I hope this helps and please let us know if we can possibly help with anything else :).

I am a handy homeowner and just installed one- but beware if you fry parts in a surge etc. like I did aprilair won't warrenty the parts. Plenty big for 2500 sq ft if it's wired to a two stage heater

Considering that the CV-400 (400 air watts) is recommended for a maximum 2200 sq ft home and the 4B-H703 (590 air watts) for an 3000 sq ft home I think you can assume it will work at least as good as your prior system.

I'm wondering the same thing. Wish someone could answer this, I'm really considering purchasing this unit.

Many issues. 36K here is an inverter model. Also it is much more expensive to build to be able to reach to that capacity in a limited space. Main reason is the economies of scale rule. Consider buying 2 sets of 018 models instead.

What Darren said is spot on. It should be fine. 75 RPM is only 7.5% (0.075) faster than the one you have now. If you still want another opinion, I would drop by the local technical college/school and find the HVAC instructor. Ask him or her to make sure. And it would be free advice, too.

If you don't use everything all at once. Mine runs one bath, kitchen and laundry, I have a small unit for second bath. One thing to check out first would be the electrical power required and it's availability. Requires three double 40 amp breakers and heavier gauge wire to carry the power. I took out a 40 gallon electric water heater and it has saved me about $60 a month so I would not go back. As energy prices get higher I save more. As with everything some common sense in using it should be observed, I love mine.

Hi! This is exactly why I purchased this! I wanted to save on energy By decreasing the central air usage. In my experience, this is great for a large room or open space. It won't sub for central air on another level of the house. I have a large living-dining area that is cooked just fine with this on the highest setting on the sweeping motion. Hope this helps. Their website gives specific dimensions for cooling area....

I have to be somewhat critical here to the lack of information given by the amazon site listing and their website. I believe the question should be what VOLUME does it cover ... and the response should be given in cubic feet ... which it isn't. So the 155 sq.ft. as listed in the manual and NOT on their website - I guess is good for 100 ft tall ceilings as well as 1 ft tall ceilings (??). (I apologize for the sarcastic answer, but they really should be clear on something like this.)

I would suggest a unit with a higher CFM speed to better, and faster, circulate the air in your shop. I have a smaller shop so the lesser capacity is not a problem.Regards, John

Greetings James, the room I have this unit in is about 2400 cubic ft and it does NOT keep the whole room at 65-70 deg only an area of approximately 8' x 8'. It really is good for a small bedroom. I use it to warm the sofa/seating area around the TV but beyond that I'd have to use the house heater. I got this to avoid having to use the house heater due to cost. It does the job for the small area only. Ciao, TLM

Hope this helps. Found this link which lists generac CSA approved units:. I just moved. Had a 20 K in last house and put one in new house. Wouldn't be without it anymore. Best purchase I ever made.

We have 2 of these units in which 1 runs almost all day and i haven't seen any difference in my megawatt usage! I was just looking at my NYSEG Bill and we're using less energy than we did last yr at this time! You'll love this unit! It can handle 3500 sqft and as long as you clean the filters once a month it runs with no problems! Had ours for 2 yrs and it handles pet odor, smoke, and cooking odors! If u check his website i think he's having a clearance of last yrs models BOGO Awesome Deal!
