Is a filter required (or highly recommended) to use on Mr Heater MH18B if I only use the 16.4oz disposable propane tanks?

The reason for the filter is because most rubber hoses have oils that get into the fuel stream, so if no hose is involved (using just the small metal container) no filter needed.

No, that doesn't come with it, however you shouldn't need it if you have a regular 20# lpg tank. If you look at the picture for the product on amazon, and then you look at the red regulator, look on the left side of it. That's a male connector that actually threads to the inside of the nozzle on the propane tank. Most people don't realize that almost all propane tanks have 2 sets of threads. 1 set of big thick threads on the outside (that's what the female coupling you asked about would use, similar to what a grill uses), then a second set of finer threads on the inside of that very same nozzle. Some fill stations use those threads. I'll put it this way, I had a propane tank, and nothing else, and the kit from amazon included everything I needed to setup the fire pit (even including the teflon tape). Nothing else will need to be purchased as long as you have a propane tank in good condition. Hope this helps!

The smaller tank is designed for it, but I bought a small hose adapter and use my large propane tank that I've had forever.

Yes it does. The filter is on the back of the heater, just remove it, clean it and put it back in place. No need for replacement filters!

James, I assume your heater and your stove are designed to use the 1# canisters of propane and that you will purchase the hose that fits a 20# cylinder and, at the other end, has a fitting that looks like the top of a 1# canister (Hose F273702).That hose feeds high pressure from the tank to the canister connection on your appliance. The appliance has the needed pressure regulator. In this HIGH PRESSURE application, you DO NEED the filter to trap any oil that is leached from the hose in high pressure uses.Jim W

The filter removes impurities in the gas that would otherwise clog the orifices and coat the catalytic causing the heater to malfunction. I have read the reviews claiming filter not necessary. It is necessary - unless you are lucky enough to get very pure propane. I tried using the heater unfiltered. It operated 2 months. Replaced it. Bought and installed a filter. 3 years now. Still operating strong. Plus, filter is too inexpensive not to use just as a precautioin.

Yes - you definitely need the filter. They can be cleaned, or a new one can be purchased from Amazon for $11. I'm happy with the unit; haven't had any leaks since I sealed the gasket with Vaseline and ensure that it is closed tightly.

I have also tried connecting a hose with a regulator on the tank to the MH9BX Buddy heater (as another said). It worked, but it was hard to lite it and with it on high it seemed like it was glowing about the same as if it was on low with a disposable tank (which I went back to almost instantly after trying the regulator so it was fresh in my mind). So I'd strongly suggest getting the F273704 hose over this because you don't need a filter with it (or need to change it), it comes with the right connections (versus you needing to adapt from the 3/8 pipe on this), and that hose will work with all tanks including 100 lbs ones.

This makes sense, you are wise to use a filter before installing the #1 canister. Also would you tell me how to vent the heater in one small room, I have windows but hate to open them, as the cold air comes in?

Yes it does. This hose feeds HIGH PRESSURE to the MH18 bottle connection. The filter is used to trap the oil that leaches from the hose in high pressure applications. Avoid trouble. Order the filter with it. It fits onto the 1# bottle end of the hose. The other end of the filter will fit the MH18 1# bottle thread.In my opinion, Users that do not use the filter are using the heater on BORROWED TIME. The filter is cheaper than a single repair to clean out your regulator and burner orifices.

I use the small propane tanks. They screw right into the valve on the back. I would assume that with a hose adapter, you could use the large propane tanks too.

It's actually not a filter system, it is an air bubbler. It was a small enough tank that I really didn't need a filter. "Bob" is a clean betta. I had no heater either. This was in my early betta learning. Hope this helped.

Filter? What filter? And why would you need a filter for just boiling water?

I checked my manual. It specifies using a 16.4 ounce disposable propane cylinder. There is no mention anywhere of whether a larger propane tank can be used. It does say not to change the regulator assembly and I'm thinking to use the larger tank you might have to. I would say no to that. And the smaller cylinder lasts quite awhile so I'm not sure why you would want to .

If you look at the reviews on the filters or at the OEM Q & A, they say that the filters are needed with most hoses carrying unregulated (high pressure) propane gas to the heater. If you are connecting unregulated gas to this heater, you must connect it to the "Disposable tank" connections so the built in regulators reduce the pressure internally. The reason for the filters are to trap oils that get "squeezed" out of most hoses under that high pressure and enter the gas stream. The one hose they say doesn't need a filter is their F273704 hose that is made "oil free", but is harder to flex as a result. If you are using the quick disconnect port on this heater, you MUST have a regulator on the gas supply. If you have a regulator directly on the tank you're connecting to, then all of the gas will be at low pressure and you don't need the filter (since the hoses are not "squeezed" much at all to make them lose the oils). If considering getting this heater and how you want to plumb it, I'd lean towards one of the options that eliminates the need for the filter. The F273704 hose may cost a bit more than others, but it's a 1 time cost and gets rid of another connection/possible leak point. Same with the regulator & QD.

It depends on whether you're using a 20 lb propane tank like you would with a gas grill or if it's being connected to a large tank that would supply your house. In both cases an air mixer is required for propane use, and then standard fittings should be connected with a shut off valve to control the burner.
