Make sure you need this filter before you buy
By DIY Guy
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.

Very important to have, unless you're using hose with Regulator
By Ken
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. Even worse, it's my experience that the filters do not do a very good job of filtering the plasticizer; perhaps because the higher pressure in the hose when you first turn on your heater blows it right past the filter.

That means that, even if you're using a filter, if you're using the older-style black hose, you still have to turn off the tank before turning off the heater. If I'm using a black hose, I usually turn off the tank and just let the heater go out by itself.

But nowadays I usually use the Plasticizer-free Green Hose that Enerco sells, so I don't have the plasticizer problem. The advantage of the Green Hose is that since I no longer have to turn off the tank and then allow the heater to just go out, I can now leave the tank outside my tent trailer and just turn the heater on and off without bothering with the tank.

Some sources say that, with the Green Hose, you don't need to use the filter. I still use the filter though, due to the problems with contamination from propane mentioned above. It's still necessary to use the filter because your propane is still going to contain contaminants that will need to be filtered.

I have 3 heaters - I date my filters (using indelible markers) when I put them on a heater and change them out after a year. I've had no problems at all since I started this system.

Mr. Heater Fuel Filter
By L. Closser
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.
