Honeywell 18155 SilentComfort Air Purifier

FANTASTIC and VERY QUIET..., February 11, 2007

"HONEYWELL: 18155 SilentComfort Air Purifier"

First off, I'd like to say that this is the only air purifier I've ever owned so I cannot compare it fairly to others so I won't even try.

First off, I'd like to say that this is the only air purifier I've ever owned so I cannot compare it fairly to others so I won't even try. But I've read dozens of reviews about the Honeywell QuietCare 17000 and noticed the main complaint is that it's not really queit at all. Well...I hope this helps.

As far as the noise level goes this SilentComfort 18155 is very quiet on MED and LOW. On HIGH, right next to it, it's about as loud as our dishwasher about 30 feet away. So it's not bad at all. I can still hear the television and have normal conversations with the family without yelling.

I've done some of my own studies to see how well the dust is being pulled into the machine and can see there is dust building up in the pre-filter over time. It seems to work very well. I've also noticed a difference on how fresh the air smells. My sneezing is almost down to zero, when it's running, and that tells me it's really working.

It does NOT have an IONIZER which IS A GOOD THING in my opinion. I've learned that these ionizers omit ozone. Which inside the home this ozone builds up and can be very harmful to the lungs. I did NOT like the sound of that so I turned away from the "ionizer" models.

It is very sturdy, a little bulky, but not too heavy to put in other rooms from time to time when I feel the need to relocate it. It blows cold air, not like a fan and not too direct, at a 360 degree radius(it also pulls from every direction). The cold air will be nice in the summer but it's not so nice right now in the winter. I like to put it next to the bed and it can get a little chilly when my covers come off. It has a very comforting and relaxing white noise hum to it. The motor runs very soft and consistant. No rattling or buzzing of any kind. It seems very well built.

MY ONLY CONCERN is that the return/exhaust does NOT blow straight up. It blows outword on the top/sides and it pulls from the bottom. This may be a brilliant design or a serious flaw? I question...is it just filtering the same air over and over again or is it like a vortex that pulls the dust into it with the pushing air(kind of like a tornado)? In my studies I found that was a tough call for me to make. But it really does help with my allergies so I must conclude that it's working properly.

I ordered it directly from Amazon and it arrived in 4 days(that includes the weekend) and that was with the FREE SUPERSAVER SHIPPING. Amazon is always fantastic about that, so no complaints there.

OVERALL... I am very pleased, though it may be a little early to give a longevity review right now, the HoneyWell SilentComfort 18155 really seems to work great and I have no complaints. If anything faulty or negative develops I will amend it into this review accordingly.

2 THUMBS UP...and I breathe much easier now. minimize

Perfect for people with allergies, May 6, 2007

I bought this air purifier because my infant was showing signs of allergies - sneezing, rubbing her eyes, etc. Within an hour of turning on this filter, everyone in the household stopped having sneezing fits and our baby doesn't have red, itchy eyes anymore. I'm amazed by how well it works. The unit is really quiet.

The only thing I don't like about it is the size. It's huge! At a foot and a half wide it takes up a lot of space. You can't easily hide this thing next to the sofa. I'm still trying to figure out where to put it so that it isn't in the way but can still filter the air. Very satified with this product overall. minimize

Nice and Quiet.
The only negatives are the instructions which do not seem to match the machine.
the diagrams (on Amazon too) show a large prefilter wrapped around the main filter.
In fact that is not how it is set up. The small prefilter goes on the bottom of the machine. The main filter is in the top and they are accessed via...read full review Nice and Quiet.

In fact that is not how it is set up. The small prefilter goes on the bottom of the machine. The main filter is in the top and they are accessed via different "hatches".
The directions also show cleaning the outside of the HEPA filter. the reality is that the way the machine works you would need to clean the INSIDE surface of the HEPA.
Otherwise works fine. My Asthma is much better. minimize

Quietest True Hepa, March 8, 2008

Pros: Extremely quiet on low.
Loud on high (you know it's changing air faster when you want it)
Not hard on the eyes.
360 intake/outake(?)
It's a Honeywell.
Cheap
Permanent HEPA Filters. (clean with a vacuum)

Cons: BIG. Not tall, but wide.

I have done extension research on True HEPA, HEPA Type, LFD, and 3M air purifiers - true hepa being the best, 3M being the worst.

This purifier is the quietest True Hepa purifier I have tested. It is much quieter than the claimed Kenmore "America's Quietest True Hepa Filter," and also much quieter than Honeywell's QuietCare models. I hear some people complaint about how loud the highest speed is. This is not a sensible remark. You WANT the highest speed to be as loud as possible. The louder it is, the more air it is circulating. The question is how silent can it be, when you're sleeping? This thing is so silent, if you put it on the other side of the room from your bed chances are you won't hear it at all. It has half the dBm of the QuiteCare and the Kenmore.

Honeywell's designs and filters are incredible. You'll feel a difference after a day. I have terrible seasonal allergies, as well as allergies to my cat. minimize

Honeywell 18155N SilentComfort airfilter, thumbs-up., April 10, 2007

very quiet for sure. it's helping a lot with my allergies. i run it 24/7 on low and that does the trick. the only disadvantage is the suggested placement, 3' from any wall. however i've got it maybe 1-2 feet from any wall and it's able to suck air from all directions.
