Is there a difference in the power of the fan, or type/number of plates between this New Comfort Hepa UV filter &amp; the NC without the Hepa &amp; UV?

The fan has variable speed. The Ch3500 has 3 filters and 2 ceramic plates. It is simplistic to clean a vacuum or compressed air to clean filters and a mixture of 50/50 ammonia and water to clean plates. no other tools required.

there is no filter or anything to catch the dust and debris.. i thought it had a hepa but nope. its just the ozone and uv. i would spend the extra nd just get the zen brand hepa living air purifier;-)

As mentioned below the air flow is a little bit restricted but it does allow some air. I went to Corsair's site and ordered their high air flow front plate. It's a front panel that is screened, yet the framing is still sporting the brushed metal face. picked it up for a mere $15.00 + shipping. Best of all, the fine dust filter that came with the stock case fits behind the new screen face. I did change out my stock 140mm fans with Cougar 140's Vortex hydro-Dynamic-bearing fans. There far quieter and have better Static Pressure than the stock fans. Plus they are PWM where the stock ones are 3 pinned. So now it's still a quite case even with the open air front.

Full measurement of the entire filter is about 140mm x 140mm outer measurement, with an effective 130mm x 130mm of filter, 10mm of magnet on all sides. The magnet will cover a slight portion of the fan, but I don't think it would significantly hinder performance. I use this filter, and honestly the dust it catches greatly outweighs the size of the frame.

I have no idea, since I have only this version. Perhaps you could print out the features and specifications of each fan and compare them that way.

Wish I could help but I do not know what the difference is. Sorry!!! What is the make and model number of your fan?

I haven't noticed any decrease in air flow. The upgrade kit and new filters make a tremendous difference in the air quality of my house - especially the allergens. Very clean.

it depends on the volume of air that the filter will flow. look at the cfm on filter and should be greater than the cfm on the fan.

Yes indeed. In fact, one of the reasons i purchased these filters was to replace other low-caliber non 3M filter media.Keep in mind however, that you may need to have your HVAC contractor check the fan motor settings to determine the manufacturer-recommended setting if you have a variable speed motor. Unless the cardboard filter frame is cut or compromised, your filter should not bend in your filter plenum.These are specifically engineered as 90 day filters but i swap them out regularly at 60 day intervals. Hope this helps!

Hi Richard. It is such a coincedence that me and my dad took almost 1400 lbs of trash to the dump just yesterday and we had to seperate trash from metal from electronics and three of those fans were part of the load. I just went out to the garage because I still had the box for the HF-910 and I was suprised the diameter was not mentioned. I can assure you it is a 20" blade. I have seen enough fans including box style and the HF-910 is not small. Good luck with longevity should you buy this model. Here is the one I purchased at walmart and sold here for $60.00...10 dollars less then Walmart ( Lasko 2264QM 20-Inch Max Performance High Velocity Floor/Wall mount Fan) Take Care, Wayne

it has a off/on and rheostat. but wont control my fan speed. on high all the time. the one I bought was the kbmc-13bv. the one I need is the kbmc-13bvns. they said the 13bv would work but it does not

Yep. Pricey, BUT the listed price is for the SET. ( Charcoal odor reducer and TRUE Sub-micron Hepa filter) so together, not as costly as some. I bought this model specifically for the micro-micro Hepa AND the pathogen destroying UV light( Like mold spores) Some larger machines can have triple the price filters so I'm good with the AC 4100! I got taken in by the hoopla of a "No filter replacements needed" model but those don't filter at the level I needed. Stuff seems to slip by the "Electrostatic particle catchers" it seems.

UV(C) passes much more ultraviolet light than UV(0) filters. Additionally, the Pro 1 coating is a little more transparent and easier to clean. Finally, the Pro1 rim is higher quality. See hoya's website below: http://www.hoyafilter.com/hoya/products/generalfilters/uvcslimframe/

The other answer is either wrong, his filter is extremely dirty, or the manufacture lies. I began measuring the power draw when I noticed my bedroom was warmer after coming home with it running on high all day when the the door was shut. Power Draw Week 1: Low: 90 W Medium: 145 W High: 189 W Power Draw on 4th Week Low: 89 W Medium: 143 W High: 185 W Power draw will continue to decrease as less air is able to pass through the filter. With less air to move, less power is consumed. With a Beach Towel wrapped around it, the 4th Week Power Draw becomes: Low: 85 W Medium: 129 W High: 173 W Some reviewers mentioned the fan gets louder as it gets older and it begins to vibrate and make a faint buffeting sound. It does that if you wrap a towel around it too, so it's likely an indication to clean the filter

I've been changing the charcoal ones about three months(that's what they say to do),and that seems to be working out ok. You can take the cover off, and see how much stuff has accumulated on the filter, and I guess make your own determination. Have not changed the HEPA yet, I will probably go for the year, and see if it looks like it needs to be changed. It probably will. It's my feeling that most companies have spent lots of $$$$$ testing their products under varying conditions, and have set up the change intervals to optimize performance. 04/12/2014 Just changed the complete set of filters after about a year. The red HEPA light came on, and I ordered a complete set. I figure the cost is about a quarter a day. Not an issue for the increase in air quality. Hint: (1)Press and hold the reset button until it blinks, then it will go out.(2) Use a small hand vac with brush to clean the sensor area, it will pick up impurities quicker, hence, the fan speed increases quicker and doesn't have to run faster as long. After a year, we are completely satisfied with the EL500.

I'm sorry Ethan but I do not know the other model, so I can't compare. This model has been excellent for my astma, I use it in my office. The is another purifier brand, IQAir, http://www.iqair.com/, that I think is better, although more expensive, that I use at home.

I would say they're comparable. I haven't detected a difference between the two fans.
