which side faces the blower?

Does the blue side or the white side face the blower?On a previous answer to this question,it tells what side catches what,but not which side faces the blower.That is the answer I need.
Asked by: Schatzi
The White side is the air exit side, so face the white side toward the blower motor.

Can this filter be used in an electrostatic A/C filter?

I have an electronic filter on my A/C, It uses two pieces of media filter that look like what is in the picture. One piece on the top of the element and the other on the bottom. The A/C company that installed the unit wants an arm and a leg to buy replacement filters from them. The technician who installed the unit said I could by the filters at Home Depot. I've been to the store and they don't carry them in stock.
Asked by: Bill
The Hammock Roll air filter media is a cut-to-fit option for any air filtration system however, the media is non-electrostatic. If your system does not call for electrostatic media this would be a great alternative.

I am purchasing a 36"X240"X1" hammock a/c air filter.

I understand why you are no longer carrying this product in the stores because the demand has lessened. I understand that an increase in price of $5 for you to keep this filter in stock is necessary.. What I don't understand is why it has TRIPLED in price. I used to buy it in store for $11.50. Now it costs $30. So with shipping and tax, a case costs $40. Is this really necessary? Am I bring punished because I purchased a wonderful a/c system that is still working after 35 years? Just asking.
Asked by: TDHJ

Customer Reviews

30 in. x 240 in. x 1 in. Hammock Roll (Case of 1) is rated 4.1 out of 5 by 9.
Rated 3 out of 5 by from Best for energy efficiency I've used this material for years. Had a metal frame made to replace the old cardboard frame filters and this bulk media fit the bill. Only takes one cut across the roll to make the perfect size pad. In my opinion all the pleated filters have too high airflow resistance, meaning higher power bills. This stuff does the job it was mean to do...keeping your evaporator coil or heat exchangers clean for efficient operation. If you want an air cleaner, buy an air cleaner. That's not your air conditioner or furnace's job. That said, I've had to return two rolls of this material because manufacturer's quality control was so bad. Fibers hadn't been properly separated and were in clumps, meaning dust holding capacity would be greatly diminished. But to Home Depot's credit, they took them back both times without a hassle. If you get a garbage batch, just return it to Depot and reorder...but be sure to contact the manufacturer and give them a piece of your mind. Maybe they'll get it right eventually...or Depot will switch suppliers.

Rated 5 out of 5 by from Economical product Economical product for making your own filters - wish it was available in store - only available online.

Rated 4 out of 5 by from Great Product, Very Poor Availability. This filter material is great for my older furnace, which requires cutting to the right length before installation. It works very well, and the price is excellent considering this roll makes 6 individual filters. The only problem is the availability, as pointed out in another review. From the day I placed my order, it was 2 weeks before it even shipped, and then another week before it was delivered to the store. Then it sat in the store for 24 hours before I called them to find out where it was. As long as you're not in any sort of hurry, then I recommend this product. Just don't expect it to be delivered any sooner than about 3 weeks. Note that the material comes rolled quite tightly inside the "sturdy carton that doubles as a convenient dispenser" which measures 33" x 7" x 7". And don't forget that the white side goes inside, closest to the fan.

Rated 1 out of 5 by from Don't Buy This Product ! ! ! This was the most pathetic Filtering Material ever made. Do Not Buy this product unless you just want to use something that won't do the job you are using it for.

Rated 5 out of 5 by from Excellent Furnace filter! This filter was a nicer quality than I was expecting, which was a pleasant surprise. It was easy to cut to size and install. However, It didn't specify whether the blue side faced in our out, so maybe it doesn't matter?

Rated 5 out of 5 by from Not Just For Filtering Air I bought this product to cover some items that spend all summer in the Las Vegas sun. The white side reflects most of the sunlight, the weave allows air to flow through, the fiberglass won't melt or stick, I can purchase it in various widths to suit my needs exactly, and at about 27 cents/sq ft you can't beat the price. Remaining material can be used for intended designed purpose.
