Custom Air Filters

2011 Harley-Davidson FXS Blackline

Harley-Davidson Softails have always shifted shape to match the custom trends of the day, from the Pro Street-styled Softail Deuce in the late '90s to the more recent, raked-out Rocker C. The new FXS Blackline's skinny rear tire and narrow drag bars mimic the Frisco-style choppers of the Hell's Angels' glory days, delivering exactly the stripped-down, vintage look that 2011 trendsters demand.

Like most new Harleys, the Blackline is little more than an artful reblending of existing hardware and styling cues. The rigid-look Softail frame, with its rear suspension hidden beneath the engine, has been around since '84, and the Twin-Cam B (for counter-balanced) engine is now entering its 12th year of production. Styling is similarly recycled. The round air filter and gray heads above black cylinders reference early Shovelheads, while the tank and graphics are inspired by the '77 Low Rider. The bobbed rear fender with integrated stoplights/turnsignals and the smooth tank strap are modern touches, but overall the Blackline looks as familiar as a pair of Levi's 501s.

Thumbing the air-cooled, 1584cc (96 cubic-inch) V-twin inspires more deja vu, thanks to the unmistakable, potato-potato soundtrack. The pistons have reportedly been lightened to let the engine rev more quickly, but the Blackline feels like every other Twin Cam we've ridden, with colossal bottom-end torque (89 lb.-ft. at 3250 rpm) that lets it roar away from a dead stop with impressive authority. There's little point in revving beyond that torque peak-doing so only increases noise coming from the slash-cut, over/under shotgun exhaust. But the surprisingly light-action Cruise Drive six-speed transmission makes short-shifting a breeze, and the overdrive sixth makes the already smooth-running engine practically disappear at highway speeds.

The power profile is perfect for blatting around town or putting along open roads, aided by flawless fuel-injection mapping and perfect engine manners. The Motor Company likewise nailed the riding position, with the low, scooped saddle hovering just 24 inches above the ground. Reasonably positioned forward foot controls and stylish Split Drag bars-a pair of delicate arches sprouting directly from the upper triple clamp-create a suitably thuggish forward slouch that would do Rat Fink proud. It's not a position you'll want to maintain for much more than 20 minutes, but you'll feel properly badass in small bursts.

Custom Air Filters For Your House —

For reasons unknown to me, the builder of my 1,700 sq foot house installed a 32" x 25" x 1" return vent where my air/furnace filter goes.  No one (that I can find) makes a 32 x 25 filter.

I had been using two 16 x 25s taped together down the middle, but Arm & Hammer stopped making them.  Those fit perfectly.  Now all I can find are 16 x25s that are really 15-1/2 x 24-1/2 and when taped together they still leave about an inch gap total on either side.

My ACTUAL filter size needs to be 32 x 25 to fit properly.  Is there anything I can do to make the intake cover a bit smaller?  Right now, all I can do is tape the filters together with a nearly 1-inch gap in between and tape really, really well.

I am currently using DuPont Platinum Merv 12 filters (they used to be 15-3/4 but are now 15-1/2 in actual size).  Custom filters don’t seem to be an option, because the sites I have found that make them also simply tape two 16s together.  This is getting really frustrating, so HELP!!  Thanks in advance.

The Problem With Common and Odd Filter Sizes

This is a very common problem. Even standard sized pleated air filters often don’t fit properly. There is just too much size discrepancy between the manufacturers of air conditioning and heating equipment.

Filter manufacturers are trying to provide a product that will fit most common applications and to do this they have to undersize the filters a bit in an attempt to compensate for these discrepancies.

The Solution to This Problem

Unfortunately this causes many problems also. The only  place to get exact custom sized filters that I am aware of is at this site . Below is a excerpt from their page.

EXACT MEASUREMENT: Furnace and Air Conditioner Filters have an actual size that is a  fraction of an inch smaller in length and width than the listed air filter size (for example, a 20x30x1 air filter is actually 19 ½ x 29 ½ x ¾ ). Please use the actual size of your current air filter when ordering custom sizes. Use a tape measure or yardstick if necessary to measure the outer dimensions for your custom air filter order.

There is a form where you input the size that you need which accepts measurements down to 1/16 of an inch. They are looking for the actual size that you need. Add the required information in all of the fields and you are given a price before you buy.
