Just a few dollars more than others on eBay for this same product, but we have them brand new and in stock, ready to ship out via UPS SHIPPING. (Barring holiday times.) BEWARE, OTHER WASHABLE FILTER MANUFACTUERERS USE GALVANIZED STEEL WHICH WILL RUST, CORRODE AND GET A NASTY "CHALKY" FILM ON THE METAL! AND THEY USE A CHEAP 25 CENT POLYESTER FILTER PAD IN THEIR FILTER! DON'T GET FOOLED! OURS ARE NOT GALVANIZED STEEL, WE USE 100% ALUMINUM WHICH IS A LOT MORE EXPENSIVE AND WILL NEVER RUST! AND WE SELL FOR LESS EVEN WITH BETTER METAL IN OUR FILTER! BE SURE TO SEE THE BOTTOM OF THE LISTING WITH VITAL INFO ABOUT WHY OUR ALUMINUM FILTERS BEAT ALL OF THE COMPETITION! DO NOT BE FOOLED BY THE OTHER SELLERS WITH VERY LOW FEEDBACK AND THEY TAKE 4 WEEKS TO SHIP TO YOU. FEEDBACK PROVEN! FREE GIFT / AIR FRESHENER WITH EACH PURCHASE TOO! MADE IN THE USA, WITH AMERICAN MATERIALS BY AMERICAN WORKERS SHIPPED BY UPS BEFORE YOU LOOK TOO MUCH AT THE PICTURES, PLEASE READ THESE NEXT FEW SECTIONS (IN BLACK) SO WE CAN EXPLAIN WHY THE GREEN FOAM FILTER IS YOUR BEST CHOICE IF YOU WANT A WASHABLE PERMANENT FILTER! WE UNDERSTAND THAT PICKING A FILTER CAN BE VERY CONFUSING FOR CONUSMERS! WE COULD TRY AND EXPLAIN TO YOU ALL OF THE PHYSICS BEHIND THE PRINCIPLES OF FILTRATION, SUCH AS VAN DER WAALS FORCE, IMPINGEMENT, DIFFUSION, STRAINING, INTERCEPTION AND SO ON.... OR, WE COULD START TALKING ABOUT THE ASHRAE MERV TEST WITH REGARDS TO THE E1, E2 & E3 CATEGORIES FOR VARIOUS MICRON PARTICLE SIZE GROUPS. BUT, WE WOULD BORE YOU TO DEATH AND PROBABLY CONFUSE OUR COMPETITORS IN THE PROCESS! LET'S MAKE IT SIMPLE, SHALL WE? MICRON, THAT IS A MEASUREMENT THAT TELLS YOU THE SIZE OF A PARTICLE. THE LARGER THE MICRON SIZE, THE LARGER THE PARTICLE. DUST IN YOUR HOME CAN BE VARIOUS SIZES, BUT TO GIVE YOU AN IDEA FOR COMPARISON, IF YOU TAKE A GOOD MERV 11 FILTER AND PUT IT UP AGAINST PARTICLES THAT ARE 1 MICRON IN SIZE, IT WILL CAPTURE AROUND 50% OR 1/2 OF THOSE PARTICLES. PUT A MERV 11 UP AGAINST PARTICLES THAT ARE 10 MICRONS IN SIZE AND THEY CATCH ABOUT 90% OF THOSE! NOW THAT WE KNOW THAT, IMAGINE A SALT PARTICLE WHICH IS ABOUT 60 TO 80 MICRONS IN SIZE! THAT'S CONSIDERED A GIGANTIC PARTICLE. IMAGINE IF YOU HAD DUST PARTICLES THE SIZE OF SALT GRAINS FLOATING AROUND IN YOUR HOUSE! THEY ARE BIG IN THE WORLD OF "FILTERS" Time for a test! WE WONDERED WHAT WOULD HAPPEN IF WE TESTED TWO FILTERS, ONE ELECTROSTATIC AND ONE OF OUR AMAZING FOAM WASHABLE FILTERS BY SIMPLY TAKING THE SAME AMOUNT AND SIZE OF SUBSTANCE (TABLE SALT WHICHIS HUGE IN THE PARTICLE / MICRON WORLD AND THE 60-80 MICRON SIZE WE EXPLAIN ABOVE.) TAKE 1/2 TEASPOON EACH, CAREFULLY MEASURED AND THEN PLACED IN REGULAR SPOONS FOR DEMONSTRATION. THEN, CAREFULLY POURED THAT SALT ON EACH FILTER AND THEN, WE DID 20 LIGHT "TAPS" ON EACH FILTER TO LET IT SETTLE THROUGH. WE WERE BLOWN AWAY WHEN WE SAW THE ELECTROSTATIC FILTER VIRTUALLY CAN'T CAPTURE HUGE PARTICLES THE SIZE OF SALT! OUR WASHABLE GREEN FOAM FILTER STOPPED ABOUT 98% OF THE HUGE SALT SIZED PARTICLES, THE ELECTROSTATIC ONLY STOPPED ABOUT 5% !!!!!!!!!!!!!!! WHICH FILTER DO YOU WANT IN YOUR HOME? FORGET ALL OF THE HOCUS POCUS AND "CLAIMS" THIS IS REAL PROOF! THE PICTURES DON'T LIE! DO YOU WANT ONE NOW? PLEASE READ ON!!!!! CURRENT FILTER CLOGGED AND DIRTY? ORDER HERE AND NOW! FIRST, I would like to start off by thanking you for visiting our ebay listing for PERMANENT FOAM WASHABLE RE-USEABLE HIGH QUALITY AIR FILTERS! With our feeback score currently over 18,000+ positives, you can rest assured that we stand behind our products and offer the best in air filtration! Don't be fooled by the "other" guys and all of their "hype" about their washable filters. We have been in the filtration business for over 25 years. We CONSULT WITH AND SELL TO : ***hospitals (super clean surgery room filters) ***pharmaceutical drug manufacturers (ultra clean room facilities) ***we also bring our expertise to you, the homeowner! ***We are not a "supply house" that sells a lot of everything, we are FILTRATION EXPERTS! SECOND, I would like to be up front and honest. Virtually ALL washable type / re-useable type filters are NOT MERV rated! These washable permanent filters are an EXCELLENT alternative! You can save a TON of money in the long run by washing and re-using these filters instead of disposing of costly pleated filters month after month and year after year. THIRD, feel free to review all of the other claims and info on the "other" electrostatic washable filters on Ebay. They brag about their filters being able to collect 165 grams of dust by the time it reaches the "needs to be washed" point. OUR FILTERS COLLECT 290 GRAMS! THAT'S NEARLY DOUBLE THE DUST HOLDING CAPACITY OF THEIR MORE EXPENSIVE FILTERS! YES, NEARLY DOUBLE! In addition, they have a restriction value of 0.12" w.g. with the new clean filter. (That's a measure of how much restriction the filter places upon your unit's fan/motor to suck the air through it. Our filters have just 0.05" w.g. initial resistance! THAT MEANS IT'S LESS THAN 1/2 AS RESTRICTIVE TO AIRFLOW! VERY IMPORTANT, WHY THESE ARE YOUR BEST INVESTMENT! READ CAREFULLY!!!!!! FINALLY, their filter is just a flat sheet of filter on the face. As you can imagine, more total surface area means there's more area for dust to collect upon before the filter gets clogged up! Our filters utilize a "pleated" design which gives you 40% more area. YES, 40% MORE area for the dust to collect on! (This explains how we whip the pants off of the competition on performance as explained in the above paragraph!) For example, a flat filter like theirs that is roughly 20 inches by 20 inches means you have a total area of 400 square inches. Our 20 x 20 filter will give you roughly 40% more with 560 square inches of surface to collect the dust on! IT'S A NO-BRAINER! PLUS OUR PRICE IS LOWER TOO! SPECIFICATION INFO: Two layers of heavy expanded aluminum, pleated together with a piece of polyurethane foam between make this filter ULTRA TOUGH AND STURDY! With 40% more surface area than a regular air filter, this permanent filter is designed for years of filtering the smallest of particles. The foam and Aluminum framed filter is a permanent air filter designed for furnaces, air conditioners, air handling units and computer applications where smaller particles of dust and dirt are needed to be removed from the air. The perfect solution for eliminating the need for purchasing a new filter each time it comes times to change the filter. Since it is corrugated, there is 40% more surface area than a normal air filter, allowing the filter to capture more dust and contaminants without having to clean the filter as often as you would be replacing a throwaway filter. CONSTRUCTION - The air filter media shall consist of 20 PPI polyurethane foam, 1/8? in thickness. It shall be non-allergenic, nontoxic, with a green coloring and corrugated between two pieces of .020 expanded aluminum, held together in a way it won?t come apart without considerable effort. This filter pad will be enclosed in a .037 Aluminum Frame, commercially known as 3003- H4, roll formed to give it extra strength. The one piece frame is held together with heavy rivets at one corner. The filter shall retain 290 grams of dust per 2.25 sq ft (20x20 filter). Resistance when clean is 0.05 wg at 350 FPM air velocity. Maximum resistance at capacity is .335" w.g. *compare that technical data to the "others" selling on ebay and you'll see why we are offering a better filter AND A LOWER PRICE! We even outperform the BOAIR filter that sells for $70.00! ...and so what if they say "these are not electrostatic"! You know that that is like? It's like saying a plastic measuring cup that holds 16 ounces of water is different than a glass measuring cup that holds 16 ounces of water! It's pointless for them to argue that or for you to insist on a filter labeled as "electrostatic", especially when they aren't even MERV rated! PLUS THE PICTURES WE SHOW HOW SUPER HUGE PARTICLES SIZES GO RIGHT THROUGH AN ELECTROSTATIC FILTER, BUT OUR FOAM FILTER STOPS THE VAST MAJORITY OF THEM! DRAIN HOLES TO WATER RUN OFF AFTER WASHING AND HEAVY DUTY RIVETS FOR STRENGTH. THIS IS A VERY STURDY AND TRUE LIFETIME FILTER! A cost effective approach to filtering air, this is permanent and will last for years when properly cared for. This filter will fit into any existing furnace. There is no need for expensive equipment to filter the finer particles of pollen, dust, and other contaminants that are found in the air as this filter has a higher efficiency than the throwaway filters that are available. Since this is a heavy permanent filter, there are numerous applications this filter could be used for. The more common uses are in home and office furnaces and air conditioner units. Other applications include large air handling units on rooftops, computer equipment, intake for vehicles and manufacturing machinery that need fresh air to keep their motors running smoothly. MUST READ, NOTE! NOTE! NOTE! Actual size of LISTED filters are 1/2 under in length and width 1/8 under in depth. (Example: 20x20x1 is actually 19 1/2 x 19 1/2 x 7/8). ANY FILTER YOU ORDER FROM THE STANDARD SIZES ABOVE WILL BE 1/2 INCH LESS ON THE FACE SIZE! THE DEPTH WILL ALWAYS BE 7/8 INCHES! NOTE! NOTE! NOTE! If you NEED A custom size OR ANY SIZE NOT AVAILABLE FROM THE SIZES SHOWN IN THE SIZE SELECTOR ABOVE , THEY CAN BE PURCHASED BY PUTTING THIS NUMBER INTO THE EBAY SEARCH BOX; 181356822949 CLEAN-ABILITY - To gain top efficiency from your heating or air conditioning unit with the PERMANENT FOAM Filter, simply dust off or vacuum excess dirt, flush out under hot water and replace. A mild detergent can be used if required. There?s no need for oils or adhesives. Because of the Aluminum material in the filter, DO NOT use a strong Alkali Solution. Drain holes are punched in the bottom to allow for proper drainage after cleaning. After cleaning, it?s important the filter is MOSTLY dry before returning it to the unit. Message us with any questions, we will be glad to help! BOAIR, AIR-CARE, AAF, our performance and price beats them all! *Trade names are used for identification only; no product endorsement is implied, nor is discrimination intended against similar materials, we are simply giving published comparison information. IN STOCK AND READY TO SHIP DIRECT TO YOU VIA UPS! THE LAST FILTER YOU WILL EVER HAVE TO BUY! JUST BRUSH OR VACUUM OFF THE BIG DUST, RINSE OUT WITH WATER, LET IT DRY MOST OF THE WAY AND PUT IT BACK IN THE UNIT! YOU'RE DONE WASTING MONEY ON FILTERS WHEN YOU BUY THIS ITEM! (LOOK AT THE NUMBER WE HAVE SOLD AS PROOF!) WANT MORE INFO???? WHY ARE OUR FILTERS BETTER THAN OTHER CHOICES YOU HAVE???? Other competing brands do everything they can to "cheapen-up" their filters so they can make more profit. To top it off, they not only make their filters with cheaper materials, they charge you, the consumer more too! Crazy isn't it? Hard to believe, but it is true. Please allow us to explain! We use 100% aluminum in all of the metals in our filters. Aluminum will never rust and is extremely hard to corrode for this application. 1. THEY USE CHEAP GALVANIZED STEEL ON BOTH THE OUTER FRAME AND THE EXPANDED METAL GRIDS! DON'T BELIVE IT, THE MAGNET PROVES IT AS A MAGNET WILL STICK TO CHEAP GALVANIZED BUT WILL NOT STICK TO OUR ALUMINUM FILTERS! 2. THEY ALSO ONLY USE 1 SINGLE RIVET TO HOLD YOUR ENTIRE FILTER TOGETHER. WE USE A MORE EXPENSIVE AND MORE TIME CONSUMING 2 RIVETS WHICH GIVES YOU A MUCH STURDIER FILTER! 3. THEY TAKE SUPER CHEAP AND INEXPENSIVE BULK POLYESTER FILTER MATERIAL THAT COSTS ABOUT 10 CENTS PER SQUARE FOOT (If you have a 20x25 filter, that means about $0.33, yes just 33 cents worth of poly filter material in it) AND THEY SIMPLY WRAP A METAL FRAME AROUND IT, SANDWICH IT BETWEEN SOME GRIDS AND CALL IT A GREAT ELECTROSTATIC HIGH QUALITY AIR FILTER! TOTALLY RIDICULOUS AND I AM TIRED OF SEEING PEOPLE GETTING RIPPED OFF! WHAT THEY SELL FOR $35.00 TO $50.00 IS REALLY NOT MUCH DIFFERENT THAN A $1.00 CHEAP FILTER FROM THE HARDWARE STORE WITH THE SAME FILTER MATERIAL IN THE MIDDLE! 4. THEY CLAIM A MERV 8 RATING. THIS IS ONE OF THE BIGGEST AND FRAUDULENT LIES GOING IN THE FILTER BUSINESS. TO GET AN OFFICIAL MERV RATING, A FILTER SHOULD BE PURCHASED ON THE OPEN MARKET, BY A TESTING LABORATORY (to prevent the manufacturer from making a "special" or doctored-up filter) and then tested with regards to the E1, E2 and E3 categories regarding particle size ranges. Dust feed rate, humidity, temperature and many other factors go into MERV testing to assure consumers it is a valid test with equal results. Ask any washable filter manufacturer for a copy of their OFFICIAL MERV TEST REPORT that shows you the Laboratory name, Lab phone number, Test report number, date and time tested, showing purchased on the open market and call the laboratory to verify it is real. YOU WILL NEVER GET IT FROM THEM BECAUSE IT DOES NOT EXIST (or they do have the test and it performs so poorly they do not want it public or published)! Anyone can make up a fake sheet, put a "Corporate Seal" on it and make it look official and say whatever they want...but THAT IS NOT A MERV TEST! Sorry to be so blunt, but I am tired of consumers being deceived when it comes to these washable filters! In fact, there are CEO's and owners of some of my competition's filters that have been charged with a felony for diluting chemicals that were made to kill off deadly viruses like AIDS and MERSA. You can do your own research and decide if you want to trust the claims by other manufacturers if they do things like that and intentionally deceive with bogus product claims! Just Google search the following words to see the public information for yourself from the FBI: air duct company sentenced 5. DO NOT LET OUR LOWER PRICE FOOL YOU! OUR FILTER IS: MADE BETTER WITH HEAVIER METAL THICKNESSMADE BETTER WITH NON-CORROSIVE ALUMINUM INSTEAD OF CHEAP GALVANIZED STEEL THAT WILL RUST OVER TIME.MADE BETTER WITH 2 RIVETS HOLDING IT TOGETHERMADE BETTER WITH HIGHER QUALITY INTERNALS AND NOT CHEAP CHAIR PAD STUFFING (THEIR WHITE POLY CENTER)MUCH LOWER AIRFLOW RESISTANCE (THEY CLAIM 0.12" W.G. RESISTANCE BUT THAT IS JUST FOR THE FILTER MATERIAL IN THE MIDDLE, NOT THE ENTIRE FILTER! SEE THE PICTURES BELOW AND I HOPE THIS KNOWLEDGE AND THE PUBLIC FACTS I BRING TO YOU HELP YOU BECOME A MORE WISE CONSUMER! Difference between ALUMINUM (OUR FILTERS) and galvanized STEEL(THEIR FILTERS) Regarding various industrial apparatuses, aluminum is preferred over galvanized steel due to its increased performance.. Aluminum products are also preferred over galvanized steel due to their anti bacterial properties and easy to clean nature, especially when there is foodstuff involved. As compared to hard and smooth aluminum surfaces, galvanized steel surfaces are porous and rough, which can hold and accumulate bacterial growth and contaminate food processing. Would you really want to use a filter made with Galvanized metal? Or, a higher quality metal that keeps you and your home a safer environment with regards to air quality? Not to mention, ours will not rust, corrode and degrade over time and multiple washings like a Galvanized filter will!
