Lifespan of S9 Autoset hypoallergenic filter?

[SleepingUgly]

I see that he regular filter for the S9 is supposed to be replaced every 6 months. But what's the lifespan of the hypoallergenic filter?

For any filter, it really depends on the environment you're in.

One thing that may help: take the filter out (I try to do it once a month) and snap your finger at it to shake dust out of it (hit from the inside to the outside), I do it near an open window, and not in the bedroom.

Indeed! When DH was installing new windows, (bless his heart)
our regular filters had to be shaken out every couple of days.
When all the carpentry was done-and cleaned up after, I replaced our filters,
even though they were only a couple of months old.
He wants to get the hypoallergenic filters next time we buy any.

Do the hypoallergenic filters go in any special way, does it matter which side goes towards the inside like with M Series white filters? Do they have any impact on the pressure/air flow?

I change my hypoallergenic filters more often--every month or two... since they are collecting more stuff, they tend to get dirty faster. You can tell by looking at them if they should be changed--just compare against a clean one and use your best judgment.

I don't think they have different sides as far as first installation goes. I only meant to make sure you shake out the dust from the "inside" side to the "outside" side, and not drive it into the filter. And then, when you put it back in you want to maitain the outside side of the filter. That does mean you have to remember how you're holding it....

In my most recent order with our hosts, I purchased a dozen of their house brand S9 hypoallergenic filters, which I intend on changing at the first of every month... they're less expensive than the brand name and are a small monthly price to pay to keep the air that is being forced into my lungs as allergen free as possible.

I notice that they're not as thick as the brand name filters, but I would imagine that this is compensated for, by the fact that they are affordable enough to be changed more frequently, thus reducing the need for a thick filter.

Nice to know someone else feels the same as I do, that the generic hypoallergenic filters do indeed feel thinner than the Resmed branded ones . Every time I change my S9 filter, I always end up spending minutes staring and comparing the generic to the brand name filter lol. I tend to change my filter monthly since I noticed that after one month, if I flick the filter, a lot of dust gets released.

By the way, our hosts here used to sell both the generic and the Resmed brand Hypoallergenic filters, I bought both from them once. I paid $4.95 for 2 (2.47 each) for the Resmed brand versus 13.95 for 6 (2.32 each) for the generic. Its not all that much cheaper for the generic. I'm just going to stick with the Resmed branded one from now on.

I set my s9 to remind me to change it every month. Just moved into a new (old) house and this month it was pretty disgusting looking, so I guess it depends on environment. I wouldn't trust just shaking exterior dust off. What remains inside may defeat any attempt at trying to stay away from allergens.
