Longevity Turtle Filters

I just received some replacement filters from Amazon for my DreamStation. While the filters appear to be the same as my original ones, I am a little concerned. I have been reading reviews and while most are great reviews, there are some that said they restrict airflow and they can cause AHI and 90% numbers to RAISE! I searched and didn't find a post on them so thought I would put this here. Anyone currently using these filters? Any issues with them? Should I use them?

Try one, see if it restricts your airflow, or causes your AHI and 90% numbers to increase.

I don't give most of those reviews much credibility.

AHI and 90% numbers can rise even without changing brands of filters and a lot of people don't realize that fact.
We don't sleep the same every night for one thing and data will change from night to night without changing anything.

Most of the aftermarket filters or generic filters for these cpap machines are so close to original name brand that it's hard to tell the difference. I have used both over the years with various machines and couldn't ever tell any real difference.

I agree with DS....give it a try and see what happens.

Last night I used an original Respironics Filter with a Longevity Turtle disposable filter as I was too concerned to use both Longevity Turtle Filters together. While the fit was perfect, I woke 3 hours into my sleep my a high pitch squeal coming from my machine. My AHI at that point was 2.8. I will also note that I used a Heated hose for the first time with the setting on 3. I hadn't used a heated hose prior, and personally I didn't love it. I turned the setting down to 1 and I removed the disposable filter the rest of the night and my numbers dropped to 1.6 for the whole night meaning those last 5 hours were really good. Makes me worry about using these filters. Don't want to hurt my machine!

So not only did you disregard the part about drawing conclusions from short term periods, you introduced other variables .

Filters are very simple components, it's not going to hurt your machine.

Failing to use a filter will do more harm than using an off-brand filter.
Filters are intended to protect the MACHINE.
If they were meant to protect you, they would be closer to your face.
Product reviews cannot be trusted--good ones can be shills;
bad ones might be competitors

I am all about using the filters needed. I am just wary of these particular filters. My machine was making a strange noise that it hadn't made the first two nights using original filters. I admit that I added a heated hose, but I didn't have the noise the rest of the night although I did turn the heat down from 3 to 1. I am just giving you my honest opinion.

Noise happens for all kinds of reasons.
Usually soft things are not the culprit.
Look closer--you may be surprised where the sound is made.

I am just giving you my honest opinion.

Nobody is accusing you of being dishonest, and opinions based on poor methodology are problematic, at best.

Which potential COVID vaccine would you be comfortable taking?

• Vaccine 1: Tested on a large sample size, for a large period of time, with all potential external factors reduced.
• Vaccine 2: Tested on a few people, for a coupe days, without removing other variables and external factors.

Which methodology does your "testing" resemble?

Your OP completely disregarded the majority of the positive reviews, focused on the few negative ones, and you didn't even experience the restricted airflow, consistent with the claims.

Your machine is data capable, but you haven't reported [or even looked at???] the events you believe are caused by the new filter?

Your sample size is non-existent, and any conclusions drawn from it, can't be trusted.

The one thing that should be explored is the squealing. This *could* be explained by a poorly-fitting filter, as well as other things; filter not seated properly, something other than the filter.

Nobody here really cares what you do, but other people may stumble on this topic and it's important they understand your conclusions are poorly formed. What's also important is; you're new here, and judging by your other posts, you seem to want to me taking a greater role in the self-management of your own therapy. Good for you, but to properly optimize, you are going to have start improving your methodologies.

Science 101....keep your variables to a minimum when evaluating experiments. You added a new filter and a heated hose...so no way to know for sure if the filter caused the noise or not.

At any rate...if you aren't comfortable using an aftermarket filter then don't use it. Buy only name brand and be done with it.
I went to Amazon and checked out the Longevity Turtle filters...for the most part people were very happy with them. Yeah, a few negative posts but for the most part more happy campers than not. There will always be a few people unhappy with anything. I always discount those and look for the overall number of happy campers when I evaluate reviews.

I look at the four, three and two star reviews as a low value guide.
I look at the five star reviews with skepticism.
I look at the one star reviews for a laugh.

Agree to disagree. 1) My AHI in those 3 hours with the filter was higher than the 5 hours after I replaced ultra thin filter. 2) I contacted the seller on Amazon and they responded today that since COVID, they had to make filters N95 compliant decreasing their flow! 3) I went out and bought original filters today! I came here looking for help and advice, not looking for criticism. While I only considered 4 STAR filters on Amazon, there were some concerned reviews. Just want to give my experience. If you don't agree, that is fine.

Huh??????

I never made the claim that your AHI wasn't higher.

I made the claim that your sample size is too small to draw any meaningful conclusions.

You just created a straw man. I never said anything about your AHI not being higher. In fact, my comments support I accept that to be true when I suggested you look at the data.

2) I contacted the seller on Amazon and they responded today that since COVID, they had to make filters N95 compliant decreasing their flow!

And you don't seem to understand that filters can and will have different airflow properties, but that will not impact the the flow through the machine. The devices will compensate by increasing or decreasing the blower speed.

3) I went out and bought original filters today! I came here looking for help and advice, not looking for criticism.

It's starting to look like you're not looking for help and advice, you're looking for people who will accept your flawed conclusions.


Now, how about if you actually criticize what I actually said, instead of things I didn't say.

The point of the post was to be wary of these specific filters for the Dreamstation. I admit my sample size was only 3 hours! But in that time, I concluded that these filters, specifically their Ultra-Fine Disposable filter caused my machine to shrill and my numbers to rise! I am not looking to debate just giving my albeit short experience with these specific filters.

That makes it Simple, buy OEM Filters and only use them. Jim
