Does anyone have experience with the different water filters on the market. What ones are easiest to install and how effective are they for removing the sulphur smell? Thanks in advance.

Any of the carbon filters will remove sulfides and the smell, however, it won't remove the cause. Rather than an endless stream of filters every time one breaks through, you might be better to eliminate the cause.
The use of bleach does wonders to fresh water holding tanks. it does produce a white flaky substance that tends to make the pump not work so well though. that stuff can be mechanically filtered out with just a generous mittenfull of plastic wool stuffed into the standard inline strainer.
Tastes great, fuller pocketbook, is it Miller time yet?

There is an inline filter for RV to fill the tank from unknown taps. It's better to keep the crap from getting into the tank in the first place.
I have two separate tanks, fresh water and a smaller drinking water tank. Fresh water filled from the tap. The drinking water came from home filtration or from super-markets (not necessary better but refill often).

To lessen 'sulphur odor' (caused by either dissolved sulphur in the intake water or by bacterial decay inside the tank) I recommend two methodologies:
1. Filter the water with 1,µM (NSF or FDA rated for 99+% of 'oocysts' removal) and put the filter ON the dock hose that you use to fill the tank.
1a. add a 'charcoal' filter of at least 2-5µM 'rating' to the exit of the bio-filter used on the fill hose, and change for a new filter after filtering ~500+ gallons or 12months which ever comes first.
IMPORTANT - fill the tank through the charcoal filter *as slow as possible* as it takes 'dwell time' inside the carbon filter to better 'strip out' chemical fragments, etc.
Completely 'dry' the carbon & 'particulate' filter when finished filling.
2. Be sure your tank is CLEAN ... no 'slimes' can be felt when you wipe your finger on the interior tank walls and the ID of the distribution piping of the water system. If 'slimes' are noted, then you should completely mechanically scrub the tank internals and as much of the 'hosing' that you can (includes the entire length of 'vent hose'). Then sanitize, etc. using common methods; if there was 'considerable' or 'noticeable' slime you may want to sanitize 'several times' in succession.
2a. Once the system is clean, sanitized and flushed ... then consider to put a small charcoal packed filter 'close' to each 'spiggot' ... change every 4-6 months. and routinely add just enough clorox to the tank water so that (when the charcoal filter is removed from its 'housing') you can detect the 'barest odor' of chlorine.
Application of charcoal filters in the boat's plumbing system will 'strip' the necessary chlorine to keep the water 'potable' from the system and tank ... and the water doesnt have to be 'moving' to do so as the chlorine will continually 'migrate' to the charcoal and thus take the spaces that would capture/adsorb the sulfur. Change such 'boat system installed' carbon filters quite often or especially when you can 'detect' the very faint smell of chlorine at the 'spiggot'.
hope this helps.

I agree that fixing the source is the answer and you must be very careful using bleach in your tanks. It can be extremely corrosive.
That being said, we fill from city water through "drink safe" hoses and always let it run a few minutes before filling the tanks. Good time to clean the deck and topsides. We add nothing to our water but we do have an under-sink carbon filter on the cold water side only. We also use a Brita filtered pitcher for drinking. No worries about safety but it does make the water taste better.
Our galley faucet is a pull-out sprayer type so no good way to add a filter there.
Tank maintenance is also important. We flush with bleach solution and rinse annually. We go through our tanks every 2-3 weeks living aboard so they stay fresh.

The first thing I would suggest is a proper cleaning of your tank and pre-filter any water going into the tank.
Once you have done this you can decide if an additional on-board filter in needed.

I installed a common household water filter unit between my water tank connection and the pressure pump. Easy to do using standard plumbing hoses with the in-place plastic waterline system in the boat.
