Brand: Aprilaire
Located in: Air Filters, Residential Media Filters, Aprilaire / Space-Gard, "501" Filter for 5000 Air Cleaner
Aprilaire / Space-Gard #501 High Efficiency Filtering Media (2-Pack) These are the original, OEM expandable "accordian" style, factory recommended replacement filters for the Aprilaire/Space-Gard Model 5000 Air Cleaner. MERV 10 rated. The filters ship like a collapsed accordian and are expanded into a plastic frame within the air cleaner cabinet. The filter is snapped into the plastic frame and held in place with existing pleat spacers. Assembly instructions are printed on the product carton. The air cleaner media in the Model 5000 can last from 6 months up to 2 years. If installed on a 5-ton system, in the presence of high concentration of particulate, or if the furnace fan is on continuously, it may be necessary to change the media more frequently. In any application, the life of the media is dependant upon the total volume of air being moved through it as well as the amount of particulate it is filtering. Filters are expanded into existing plastic frame and held in place with existing pleat spacers CLICK HERE FOR STEP-BY-STEP INSTRUCTIONS ON CHANGING YOUR FILTER

Comments about Aprilaire Aprilaire / Space-Gard #501 High Efficiency Filtering Media:

Doing this myself makes a big difference in the overall maintenance cost of heating and air conditioning servicing. The installation company recommended I do this to save on yearly costs. So twice yearly I'm $150.00 happier.

Comments about Aprilaire Aprilaire / Space-Gard #501 High Efficiency Filtering Media:

[...] Installation was easy as all the step by step instructions were clearly printed on the outside of the filter box. I checked a "con" box above regarding the effectiveness of these systems. I replace my filter every year and I am surprised that the filters aren't completely filled with dust particles. I know we have dust in the house since it always settles on countertops, tables, etc. I realize that the system can't remove these particles but given they are there the air must be filled with dust which after several weeks the air filtration system should clean. However, I don't see that or a large build up of dust on the filter. So I wonder how effective this system really is......

Our whole family has significant allergy issues, and these filters are the best. You need the proper system installed, but the AprilAire system is great. Secondary benefit of moving the filters to the handler from the returns is that the house is MUCH more quiet.

Comments about Aprilaire Aprilaire / Space-Gard #501 High Efficiency Filtering Media:

We just moved into our home and had to clean the entire April Aire unit. It took a long time as it was very dirty. From here on out, it should be much easier. It is nice to just have one air filter to worry about and to only have to change it about once a year making it very feasible when compared to other air filters.

Comments about Aprilaire Aprilaire / Space-Gard #501 High Efficiency Filtering Media:

I've used these filters for years but on my recently received Aprilaire filters the edges of the filter folds were split in a number of places. This allows unfiltered air through the filter (very bad for a system totally designed to provide good filtering). Aprilaire manufacturing and quality control are slipping,

Won't completely eliminate dust in your home but keeps it down to a minimum. Changing the filter takes about 30 minutes but is only required twice a year in my home. I have changed these filters in my home about ten times now and ripped the filter one time so be carful. Overall, I am happy with the performance of this product.

Fragile media, rips and tears easily
By PlummitVerified Reviewer from Long Beach, CA on 5/30/2008
Pros:
Good media unless damaged
Cons:
OEM media tears too easy
Best Uses:
Home
Describe Yourself:
Licensed Contractor
Bottom Line:

Comments about Aprilaire Aprilaire / Space-Gard #501 High Efficiency Filtering Media:

This filter is far superior to the 1" filters used in most applications. Unfortunately the media is easily damaged on the folds and needs to be carefully handled to avoid tears and rips. Users should inspect the folds for thin tears at the fold creases. I've seen this happen multiple times and it makes the media useless as dirty air passes right though.
