Biotene Odor-Reducing Air Purifier Replacement Pre-Filter, HRF-B1/Filter (B)

This pre-filter works very well at trapping larger dust particles and leaving the smaller ones to the main filter. I think I must live in the dustiest house in the dustiest place on earth and we have several honeywell air purifiers, this one is in the bedroom. I can see through the grill on the machine when it is white with dust and I carefully remove it and vacuum it off thoroughly before putting it back again. One pre filter has lasted a year so far and seems ready to keep on truckin'. From experience with previous purifiers and filters I'm issuing a warning against ever rinsing this in water. It seems like this would be the easiest way to clean it but it only causes dust to become glued to the material which plugs up the pores and renders it a lot less useful.

Everyone in our family was suffering from allergies and waking up congested every morning until I got a couple Honeywell air filters for our bedrooms. I change the odor-reducing filter every 3 months and the HEPA filter annually or so (the air filter lights up when the filter needs changing, so I don't have to remember to do it). I'm amazed how much dust it captures and we all definitely notice a difference -- no congestion in the mornings anymore.

This is part of a 3 part filtration system for my HEPA filter. Trying to find the N type box filter replacements at an affordable price from Honeywell is impossible. They now charge you $66.95 for one pair and you need a pair for it to do it's job. This B+ is a prefilter used to get larger particulates and eliminate odors using carbon which does work. To replace the N filters though I've found a company who DOES sell them for a reasonable price and they ARE the same as Honeywell's N. The only difference being the frame is made of rubber and the Honeywell versions were framed in plastic. Doesn't matter as far as use goes, I get the same efficiency and results at a reasonable price. You can operate without the B+ filter but why? All you're doing is shortening the lifespan of your N type filters which are also more expensive. The large dust particulates will clog up the N filters in no time. The B+ I can wash for one more use and then order a new one. Just common sense here.

This little filter along with the primary (filter) are making a difference to my indoor air quality. I live on a busy street, so dust is always an issue, yet with this filter I see less dust, which is a plus for me.

The pre-filter in my Honeywell HPA-150 air purifier was clogged with dust and pet hair, so I ordered this HRF-B1 to replace it. Several reviewers have pointed out that when they purchased this product they received a knock-off or something that looked different from the picture. For those of you considering ordering this filter, pay close attention to the seller of the product. Some vendors "game" Amazon's system by undercutting the Amazon price and offering free shipping so that they appear in the seller list above the Amazon entry, and the top one becomes the default seller on the main product page. Take a look at the section directly below the price for the words "Ships from and sold by...". If it is not Amazon, then you may be buying the product from a different vendor. When I viewed the product page before ordering, I noticed that the default seller was not Amazon, so I clicked on New seller listing link below the summary (http://www.amazon.com/gp/offer-listing/B0063KBJ7O/ref=dp_olp_new?ie=UTF8&condition=new), then scrolled down until I found the Amazon entry, then clicked the Add to Cart button next to it. This ensured that I would be ordering a filter sold by Amazon, rather than a different vendor. The price was a little higher than other vendors, but I knew that the filter would come from Amazon and would be the exact item shown on the page. I did this and the product I received was indeed the one shown in the picture and came in a Honeywell box in good condition. So if you're thinking about ordering this product, check to make sure that you're buying it from Amazon to guarantee that the product is OEM and comes in Honeywell packaging.

Perfect replacement fit for my Honeywell Air Purifier. Does the job and convenience of shipping right to home.

Excellent and original product. The only place I found this affordable.

I was glad to see this available since i had an older model. easy to install

No parece ser original, solo parece una fibra doblada contra el original del equipo, tampoco corresponde él tamaño y no desactiva el sensor del filtro continúa solicitando revisar el pre filtro, la caja venía medio dañada y aparentemente abierta

Work well and clear the room and its does help with dust and pollen.

To clean the air quality in my home,in which i do notice.I find that the air is a lot more refreshing and breathable.A little noisy when you have it at the highest setting.The pads are a good source of filter.I'll give it a 4 out of 5 rating.

It looks thinner when I received the project

As other reviews have mentioned they aren't like what came with the air purifier. I have found that using two of these works. Vacuum one layer and put it under the other. These are expensive though. I also rinse mine and hang dry them and use them doubled up (two together in the air purifier - they fit).
