How long does this last? Does this need to be done every 6 months or so?

Hard to answer this question. Many variables such as how much traffic,how often you vaccum,are you shampooing carpet,etc. I like to spray it on every 6 months or so. We have 2 small dogs and grandchildren every once in awhile,can't hurt the way I look at it. Especially in the traffic areas.

I only applied it on e, when I first put rug on the floor. Seems to still be working ....

I just use it right after I clean my carpets. I don't put it on again until the next cleaning.

I keep getting spots on my carpet. Don't know if they're the same spots or new ones. But the stuff makes them go away.

It is replaceable, it is washable, instructions said to change it out every 6 months.

I have not followed the 6 month change but as the other post says it does get grungy after continued use - it will eventually fail burn out (not work). The 6 month maintenance sounds safe - seems like my diffusers last about a year plus, not more than 2 years. I have to admit I did not read the instructions just used it like a air freshener.

We use ours to filter septic gasses and replace it every six to eight months

The filter lasts for at least 6 months. If you don't use it much then it can last more than 6 months.

I go for 6 month routine dental cleanings. My dentist hasn't said anything about damaging my teeth. It's pretty effective, so I don't use it daily.

Depends on the conditions to your particular environment. Mine can make it to about 6 months, but I change every 3-6, depending how dirty it looks when I check it periodically.

It depends on how long you use it for. If you are doing it for a straight period of time you probably need to fill it every few hours or so.

The owner's manual says replace every year for heavy use, every 2 years for normal use and every three years for light use. I use it only at night as opposed to the recommended constant 24 hour condinuous use, so I think I probably waited 4 years, which was much too long as it was really dirty.

2 things that I have to say is "don't let no one use your roller and always clean your roller after using it" if your using it weekly I will say 2 months and if it's monthly (like I'm doing) every 6 months.

This filter is intended to be changed every 12 to 24 months. It is recommended that the average household change it every 12 months for optimal performance and 18 months for optimal value.

I will be using this May through October (six months/seasonal). Depending where you live you could try using it that way and if your pet has a problem, then you will know you have to use it for a longer period or all the time.

On the old models I changed every 30 days. This one, with filter A, says it will last 3-6 months. I haven't had this one long enough to know for sure.

I bought this as a gift for someone who works on it as a hobby. I would say 3 to 6 months if you are only working on it on weekends in your spare time.

They recommend replacing it every 6 mos. I don't. I originally had a counter top version, but they recommend 6 mos. I probably replace mine every 8-12 months. Like you, I mine for drinking and making coffee. Aquasana was highest rated when I looked around, before buying.

Manufacturer should respond, but the instructions say every 4-6 weeks, I believe
