"Breathe-Easy" Platinum Catalytic Filter

They are all gone, sold out. 

The Breathe Easy filters were made over two decades ago. The manufacturer priced them at about $20 and sold few before going bankrupt. My supplier purchase the residual inventory in bankruptcy proceedings. Several years ago I purchased all remaining stock and sold them all. There will be no more of them, but it is possible that a few may turn up on eBay or similar forums.

I will leave this page up for those who have a Breathe Easy
and need installation instructions.

Example of installation in a radiant heater

Installation in Perfection heater and Aladdin Blue Flame heater

"Breathe Easy" Platinum Catalytic Filter

The "Breathe Easy" Platinum Catalytic Filter is a platinum-coated screen, 6 inches in diameter, which is hung by three stainless steel wires to just above the flame on a kerosene heater burner unit, as shown in the illustration above, right side.  It was designed to reduce odors and films and help a kerosene heater burn cleanly.  Installation is not difficult, and the unit comes with installation instructions. (Thanks to Knox Crowell for these enhanced instructions!)  The Breathe Easy is rigid mounted (see below) or hung by the supplied wires and should be at least 1'' above a flame spreader or catalytic converter burner unit to allow normal airflow for proper combustion.

Do you need a "Breathe Easy" Platinum Catalytic Filter?  A properly adjusted kerosene heater with a tall catalytic converter (burner unit) already burns extremely clean.  However, there are some circumstances in which a "Breathe Easy" can be useful:  (1) Those who have a heater with a short burner unit (early KeroSun heaters); (2) who have particular lung problems; (3) burn a kerosene heater all night long in a well-sealed house to keep the chill off the house; or (4) who burn poor quality "red dye" kerosene, may find the Breathe Easy a handy accessory.  Some very nice people have used the Breathe Easy and report great results.

The "Breathe Easy" Platinum Catalytic Filter is 6 inches wide and will not fit some heaters, such as the "Moonlighter" and Omni 15, without cutting off the stiff wire around the screen. 

It would be neither fair nor objective for me to give illustrations of the use and installation of a Breathe Easy Catalytic Filter using my own heaters, so the examples given below are unsolicited examples sent to me by my customers.

Please note that flame spreader heaters such as the Perfection and Aladdin Blue Flame shown below can indeed make the Breathe Easy glow red, whereas installation in a modern catalytic converter style heater usually does not show any glow at all from the Breathe Easy.  The reason for this is that flame spreader design heaters produce ALL of their heat from the flame above the flame spreader.  Modern radiant heaters use a catalytic converter to absorb virtually all of the heat and reflect it into a room.  The heat output for both types of heaters is about 10,000 BTU/hr, but the heat is distributed in an entirely different way.  An illustration of a dimly glowing Breathe Easy Catalytic Filter on a radiant heater is below.

Independent test results using the Breathe Easy in a Perfection heater:

"The (tests) indicate an expected reduction of Carbon Monoxide by about 85% and Hydrocarbon emissions by almost 100%. Observed performance showed no impact on heat output or visual impact of the flame nor Flame Spreader. Shutdown produced only a brief whiff of fumes then just decreasing clean heat until unit cooled down. Catalytic disc stayed in place during the lighting process with the chimney laid on its bail handle.  Conclusions: The ability of the Perfection heaters utilizing the #500 wick to come up to full operating temperature quicker than a modern kerosene heater is an advantage. With the Catalytic filter disc in place, the unit can be shut down without filling a room with un-burnt kerosene fumes." https://groups.yahoo.com/neo/groups/KeroseneHeaterandStoveCollector/conversations/topics/3647

Below is the article, stolen from Kerosene Heater and Stove Collector Forum, Greg Hall, author and photographer of this article.

Catalytic Filter Upgrade For Perfection Kerosene Heaters Utilizing #500 Wick Assembly.
Parts Needed: 1-"Breathe Easy" Platinum Catalytic Filter from Miles Stair
1-pack of 3ea 10-24x3" stainless steel pan head machine screws
(Home Depot 30699 31561)
3-packs of 4ea, 10-24 stainless steel nuts (Home Depot 30699 32011)
Note: Kerosene utilized for this testing is Canadian #1 Stove Oil w/15 ppm sulphur content.
Images will be posted in the Photo Section under "Catalytic Filter Conversion"
Why Upgrade: Original Patent literature claims use of the "Breathe Easy" Platinum Catalytic Filter converts un-burnt hydrocarbons and carbon monoxide into carbon dioxide and water vapor. For more info see U.S. Patent # 4456702, June 26,1984. Reduce shutdown fumes.
How to Upgrade: I started with a standard Platinum Catalytic Filter disc from Miles Stair. What you get is a 304 stainless steel wire mesh screen coated with a Platinum catalytic coating applied directly to the screen. As delivered the disc's hanging wires were too short, leaving the disc too far above the flame. This was not unexpected due to the fact the unit was designed for a "modern" Japanese kerosene heater. Also the hanging wires would become dislodged when the top was opened to light the burner. To move the disc closer to the flame, I drilled the wire holes larger with a 3/16" drill bit and inserted a 10-24 3" stainless steel pan head screw in each hole, retained by two 10-24 stainless steel nuts, one on the top of the disc and one on the bottom of the disc. This assembly was placed on the sloped surface surrounding the burner and burn tested. Operation of the heater, once up to temperature was unaffected. However while I had hoped the 3-legged disc would self-right itself when the chimney was swung upright, this was not the case.. The 3-legged disc was centered on the slopped shelf surrounding the burner assembly and the positions of the legs marked. Drill 3x 3/16" holes. Remove the legs from the disc and inserted through the plate and tightened with a 10-24 stainless steel nut. Each leg had a nut screwed onto its threaded shaft and the legs were bent into position for insertion through the catalytic plate. Disc now resides about 2-1/2 inch above the flame.

Performance Evaluation: Surface temperature of the Catalytic Filter disc averaged 600F - 650F. Graphs lifted from the original U.S.Patent.

The attached graphs indicate an expected reduction of Carbon Monoxide by about 85% and Hydrocarbon emissions by almost 100%.

Observed performance showed no impact on heat output or visual impact of the flame nor Flame Spreader. Shutdown produced only a brief whiff of fumes then just decreasing clean heat until unit cooled down. Catalytic disc stayed in place during the lighting process with the chimney laid on its bail handle.

Conclusions: The ability of the Perfection heaters utilizing the #500 wick to come up to full operating temperature quicker than a "modern" kerosene heater is an advantage. With the Catalytic filter disc in place, the unit can be shut down without filling a room with un-burnt kerosene fumes. The 11000 BTU output is perfect for supplemental heat whereas the 22000 BTU output of the larger "modern" convection heaters can be too much except in the dead of winter.

The outlay for parts is modest and the conversion time, assuming the thru bolts of the Perfection heater can be removed to allow access to the burner plate, is under 45 minutes. If a Perfection kerosene heater will actually be utilized as it was originally designed to be operated, as supplemental heat and not a display piece, then this conversion is worthwhile. Finally this conversion does not detract from the visual appeal of these antique kerosene heaters.

Last week I bought an almost new Aladdin Series 15. It had only been used for a few times. Lucky me !!

Unfortunately it smelled like heck, even using good quality kerosine.

So I resized one of your catalytic filters, mounted it (it is visible behind the mica window) and the odour completely vanished!!

Breathe Easy installed in a Yuasa Sunglow 20 radiant heater

Hello there. Just wanted to share with you a photo of my finally finished 100% restore of my old "free rescue" Yuasa.

Your wicks are just the best and the platinum filter absolutely reduces emissions. I adapted one for this unit and one for my 23k btu convection unit.

Thanks again!

Breathe Easy installed in an Aladdin TR2000 - The minimum clearance should be one inch, as shown below, to allow normal airflow and proper combustion.

There are many ways to install a Breathe Easy Catalytic filter in a radiant heater.  The Aladdin TR2000 had no way to hang the filter so 6 x 32 x 2'' screws were used up through existing holes in the top plate of the catalytic converter.  This method allowed a vertical adjustment of the Breathe Easy with up to almost 2'' of clearance above the burner.  The Breathe Easy glows a little over a catalytic converter  burner, as seen at right, but does not get cherry red as on a flame spreader heater because the burner unit itself absorbs and reflects heat before that heat can get to the Breathe Easy.
