I bought the Mr. Heater Hose with a regulator and quick disconnect fitting for the Big Buddy Heater. When it arrived, I discovered that I could not connect the fuel filter to the quick disconnect fitting. I called Mr. Heater, and they informed me that I didn't need the fuel filter if I was using a hose with an attached regulator. It would have been nice if Amazon had indicated this fact when I purchased the filter. But, none of the specifications for the product demonstrated this redundency. If you buy the hose with the regulator, then you don't need this filter.

First of all, the filter is unnecessary if you're using the hose with attached regulator; the regulator will remove any contaminants in the propane (Apparently the Amazon package unnecessarily included both the hose attached regulator AND the filter...)

Beyond that, if you're using a hose that does NOT have an attached regulator you absolutely must use the filer! I've been using Mr. Buddy Heaters for years and can attest that if you use a hose and don't use the filter, you'll end up tearing down your heater, buying new internal parts, and rebuilding it (or just throwing it out and buying a new heater, if they're on sale...)

The filter removes oily contaminants that are present to a greater or lesser degree in the all 5 gallon propane tanks (the degree of contamination depends on your source of propane). Mostly the contamination is the oderant (mercaptin oil) they add to the propane. Over time (maybe 5 to 15 tanks, depending on how bad your propane is contaminated), the oil will build up and clog up the heater's internal parts, rendering some useless and requiring cleaning of everything else.

It's impossible, by law, to buy propane refills that are mercaptin free; therefore you will ALWAYS have contaminants in your refillable propane tanks.

You can also get contamination if you're using the older style black hoses. They contain a plasticizer that will bleed out of the hose if you turn off the heater before shutting off the tank valve; the pressure builds up in the hose and forces the plasticizer out of the hose material and into the void of the hose. When you re-start your heater, all that stuff gets sucked right into your heater, and it seems that it's even more damaging than the oil in the propane.

I bought my second fuel filter and I tore the first one apart to see what had collected inside. This unit is not a "filter" per se. It is actually just an empty chamber. The propane goes in the bottom, hits a baffle, and then goes out the top. This gives the oils a chance to separate from the gas and collect inside. Judging from the amount of accumulated oil in my filter after one tank of propane, this thing is probably good for 4 or 5 tanks.

I camp out all year long. I purchased a Mr Heater Portable Buddy heater to heat my tent/quad trailer this last year. The manufacturer recommended using the filter when using bulk propane tanks to fuel the heater. It worked so well on my heater (no fuel related problems in the last 12 months) that I also installed one on my Coleman two burner stove which I have hooked to a 20 lb tank also. For the small cost, it really saves you a lot of problems with propane contaminents and maintanence costs.

Buyer beware! This item is NOT compatable with the quick disconnect hose & regulator (F271803) that Amazon suggests buying together as accessories for the mr. Heater. Shame on Amazon this time for recommending these together This filter is threaded.

First the filter can be screwed on to a Portable Buddy Heater and a Big Buddy Heater. You have Propane gas that can run through hose and the propane is under high pressure. When the pressure drops or when the heater is turned off, the organic substances in the hose can escape from the substance of the hose and enter the lumen or empty space of the hose; with the drop in pressure, the substances in the wall of the hose flow in the direction of least resistance and this is into the lumen. This liquid like matter can, over time, get into the heater and the heater will lose in efficiency as it blocks the channels through which the gas flows before it is burned. So instead of a bright red glow on the heating plate, it will be a much duller red color.
I tried a step down gas regulator but the heat was not the same. The purpose of the filter is to trap the liquid organics before they can get into the Heater. Sort of like the oil filter or fuel filter on your car that is there to prevent damage to the engine, and periodically you change the filters. I have not read any where how many hours of use the filter should have before being exchanged. Maybe some one has done that. I think if you used a copper tubing with the correct fitting, you could get away from the Fuel Filter but the low cost of the Filter tends to lead me to just changing the Fuel Filter.

I knew I needed one of these to prevent 'gumming' and decay, since we were installing a long RUBBER supply line. The price BEAT the local "discount" supplier and delivered with OTHER stuff for FREEEeee! Still running 2nd winter with Mr Htr, 12 ft hose and with this filter.
