The Filtrete Ultra furnace filters are the best I have found, and being able to order a pack instead of just one is really convenient and makes for a great value.

  Filtrete Ultra Allergen Furnace Filter
Reviewed by: Allergy Sufferer from Southern California

This filter does a good job of filtering out whatever was triggering my sinus allergy. I previously tried using a permanent style filter from my local hardware store, but found that it was not posssible to clean it as recommended. If you put water on dust, it just clings and won't rinse out, So, I switched to these disposable filters. It's worth the small extra cost to not have to struggle with trying to clean a permanent filter, and it works better. My furnace uses a filter size that's not easy to find, so I was happy to find this in the size I needed:14 x 24 x 1. Although I knew AchooAllergy had the size I needed, it is hard to locate it on their website because their are several listings for this filter, and most come up with the list of more limited sizes. I have to search long and hard, but finally get to the right selection where there are more size choices. This is reason for one less star. Shipping was quick.

Customer Q & A

Q1: What is the best furnace filter for people with allergys?
A: In reality, many of them are going to offer very similar performance. The MERV rating is the key feture to pay attention to. The nearly all disposable filters have a three month lifespan, and most are electrostatic to increase the filtration rate. The higher the MERV rating though, the greater the overall number and the smaller the size of particles that the filter will capture. Generally MERV 11 is one of your best options since it captures the common particle allergens that affect most people. A good furnace filter isn't the only solution, but it is a good first step. Lastly, just remember to change them. The reason for the 3 month interval is generally by that time, the electrostatic properties have been used up, efficiency can some but more importantly, they're often dirty enough that they'll begin to impede air flow through the HVAC system putting strain on the blower and motor. Of the 3M, the Ultimate have the highest filtration rate followed by Ultra then Micro. Either of the first two are good for people coping with moderate to more severe allergies and asthma. Hope that helps!
