HiHow would you clean out the side filters on this model?

Thanks Gareth. I live in Texas and got myself a Keystone portable similar to yours. It works great and cools my workroom very well. This is its third summer and I need to take it apart to give it a good cleaning. Mine would cool the room 30 to 40 degrees cooler than the outside temperature with a single hose. You need to send that one back and get a better unit.
I also hot-glued some SS screen on the outside exhaust piece to keep insects from trying to get inside the hose when the exhaust isn’t blowing.

I’ve got the exact same model and yea they are quite noisy, but all the portable ones are. I only run it in the bedroom for a couple of hours before bed on hot days, it does cool the room down pretty quickly. If you want a quiet one you need a split system, but it will cost about £1200 per room and you need space outside for the inverter (which is also quite noisy so you can’t have it near a window).

You also have to consider that running an aircon unit costs per hour what a fridge costs for a whole day. So you don’t want to be running one all day unless you really have to.

Informative useful review Gareth. Living on my small boat which luckily has a small drain hole into the bilge under the floor, so draining the water should be automatic. Thanks.

any recommendation for a quieter model in uk?

Nice review! What does the compressor sound like when it turns on? Is there a buzzing/whirring sound? Thanks.
