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

No. It is only advised when using re-usable bottles. (However, the filters are not compatible with the regulator included hoses which are also required! Go figure...)

meaure the disposable filter you have in the unit. That will be the size you need.

Can I assume you mean Gas Liquified Petroleum? If that is what that means the answer is yes. I use a 20 lb tank I swap out at Winn Dixie or Home Depot when it is empty. If you use propane tank you will need extension hose sold by Amazon also. Great little grill that will handle cooking for 2 or 3 people easily. I love mine.

I have not needed a filter and I use only 20lb tanks. Just use the provided hose and it'll be fine.

Hi WSong, I use #2 filters for both the large and small Bee House drippers. I don't use either of those brands so I cannot say which might be better.-Brian

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!

Depends on the actual tank. Remove your control head on the sears unit. You need a 2.5" threaded opening on the tank and a 1" riser tube.AFW Filters

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.

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.

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.

Yes, go to a propane store and purchase the correct hose and fittings, or ask them to do it for you. I have a Wave heater in my houseboat and another in my shell camper. I had an RV store install the Wave in my houseboat, and did the camper myself. The installation requires a gas filter, either on the tank or in-line.

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

Those are the "Stubby" disposable cylinders that it is designed to use. A hose, regulator, fuel filter, and adpater are available to allow use for the large barbecue tanks, but you are not supposed to use those indoors. I find the stubby disposable tanks last a couple of hours at full power. I have a few items that use these, and found some at Ace Hardware for $3.49, so grabbed a bunch.

a regulator is not required nor is a filter. I just attach mine to the tank valve

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

As others have said, I use a sediment filter on the inlet hose for my RV. Which filter element you use depends on your use.

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.
