How do I know if this is the right size? And how often should they be replaced?

I just took a shot in the dark it looks like the old one. I dont usually change them but the old one had a tare in it and didn't have a choice.

Which filter do you have? That will help me help you on the size. As for replacing, you really shouldn't have to unless they tear or perhaps your tank gets really sick so you may want to change if to rid remnants of illness. I changed mine due to a rip and really, really yucky water so we could start with a fresh filter situation.

You should have the # of the wheel in your filter booklet.. And chance the wheel once a year..

There is a different size biowheel for each individual Eclipse system. I have an Eclipse 2, but I believe there are also Eclipse 1 and 3 systems. Marineland stated when I purchased my system that you are not supposed to replace the biowheel unless it is damaged. I set up my tank in 2007 and only replaced it this year because the material had become loose and frayed and would no longer stay on the wheels. It is important to NOT change the biowheel unless it is damaged because it actually controls and maintains the good bacteria in your aquarium which will keep your fish healthy.

The size is simply matching its number. But they don't actually reccomend changing them ever. Their purpose is to provide bio-continuity to your tank. So water changes etc quickly return to balance. If you do change, do so one at a time and wait a week or so before changing the 2nd.

Go to their website and scroll to the bottom of the page. there is a place about warranties and replacements. Click it. I assume you will find what you need there. I haven't had any issues with mine but that's where I would start.

I haven't had to replace mine yet (six months daily use) but others have said it's an odd size.

Take one of your remaining blade holders and place on paper -- holding it steady use a pencil to mark where the holes are at on the paper - I also traced around mine, but I don't think you have to do that -- it is the most accurate way to get measurements for what you need for replacement. Then if I remember right I did an internet search on the this blade vs. my measurements to make sure -- and there was a drawing out there that indicated it matched up -- and it did perfectly :) Good luck!

You are better off just getting a new one when needed because you have to be careful on how and where you store them. Best rule of thumb is to change them every 3 years with a fresh new battery.

If you have a filter that you change regularly in your furnace, this will replace it. Measure the one that is currently in your furnace to make sure it is the right size.

When you go to the amazon.com site to place the order it will ask for your model# input it and it will tell you the size you need. My son just happened to break ours in half so we could measure it. But the replacement was perfect!

Yes these will work for you and the ones that I replaced are still working fine and it's a easy job changing them out... just look on youtube for a visual aid and you'll be fine.

I dont think that this product is the right one. I have ordered several sets of these and I always use the "make sure it fits" function. I have never had any problems.

Check out the companies website. It lists exactly how to determine the correct size.

That's exactly what I have. The size should be (4). They work wonderfully together and that's all I use.

The last time I replaced mine, I measured the diameter of the speakers (in millimeters) and then shopped Amazon for replacement ones that fit that size of headphones. Previously, they had always sent me really large Koss ones that I had to throw away.

I just got another order and the small/medium size was exactly what I ordered in the past. You might want to get in touch with the company that you placed your order with and find out what the problem may be. They are expensive so I would find out what went wrong. Also, you could go to the Breathe Right site and ask if they have changed the size of the strip that you ordered. Because of the expense, it is not worth keeping something that is not going to work for you. That is what I would do.

The company advises to replace each year but I have used them up to three years before replacing. I purchased this last year and did not realize how big they are. You may want to purchase smaller bottles.

They are the size and the shape. Go to the manufacture's website to check them.

probably, the sizes are standard plumbing sizes. but whether you can find an exact replacement is a question.
