Where is A/C condensation line filter?
Where is my AC condensation line filter? My leased condo is one among 20 units in one building, Building has central AC and heat for each unit of 20 units. I got HOA notice that I should change AC condensation line filter. I only know the unit has HVAC line filter, and I should replace HVAC pipe filter, which is in my unit. Is there any different between HVAC blower/pipe filter and AC condensation line filter?

They sometimes install a neutralizer in the drain line but I've never heard of a condensate filter.
Typically the condensate line needs to be flushed out. Maybe that's what they are talking about.

I know of no filter device for the condensate drain.
The filter drier on the liquid line needs a technician to change as it involves the handling of refrigerant. It doesn’t need changed unless there’s a reason.

Our below unit complains there is water coming from our unit. Our central AC and Heating station is set out of the building and is supplied for all units, cold air and heating air are transfer from underground pipe. So, condenser unit should be there or at each unit? I got HOA notice that I should replace line filter. Is it possible Air filter, I have blower set inside my unit?

If heating and cooling are done via a central hydronic plant there will be no condenser at your unit.
It sounds like you need to clean your condensate drain.

Ask the HOA where it is. .............

I think you may be not accurately interpreting what is being asked of you.
If you post exactly what the letter says without any personal info we might be able to offer more appropriate advice.

You might ask them for clarification since there is no such animal.

You’d have to ask the hoa. There is no such part on an air conditioner.

They probably mean that you should replace the blower fan filter. A dirty filter is usually to blame for a dirty evaporator coil, which in turn can produce crud in your condensate line, which will eventually plug up from all the gunk.
Typically the condensate line just needs to be blown out with some compressed air.

Some air handler/cooling coil drains may have traps or filters to keep bugs and other creatures out.
If that drain is blocked by whatever, condensate water backup can be an issue.
Another problem comes when water in a drain trap freezes in cold weather and cracks the line. Next season there is a leak.

Since you mention central hvac..... your system is probably just a coil and fan as it would get hot or cold water from a central plant. There could be a filter in that line but that filter won't cause your unit to leak.

Not sure if we're on the same page Doug.
Building has CENTRAL heat and A/C. That tells me there is a water system there. In that flowing water system can be a filter or a strainer. It does not leak any water. It has nothing to do with a condensate drain.
Yes.... condensate drains do clog relatively frequently. Yes they need to be cleaned. Yes they can be damaged and leak. However there isn't a leak. The OP is asking about a filter.
Have you even seen a filter in a condensate drain line ??
I haven't.

On DIY.com it is not uncommon to see a reader make incorrect interpretation of data then in a post send things off in crazy directions. In this thread condo management sent instructions to unit owners to change filter. The logical implication is that there are filters. Even if the owners have not seen them they should do a reality check and look.

Those aren’t filters you posted. The one is for acid treatment for a condensing burner.

I googled for "ac condensate filter" but did not edit out other types found in link.
A number of those in the link are specifically for AC condensate, the subject of this thread "Where is my AC condensation line filter?"
Because Pjmax had not seen one there was question of whether they exist. He then went off in irrelevant direction that can add confusion to basic question.

Sorry..... I see NO condensate "filters" shown in your link.
Back in post #2 I mentioned the neutralizer. That is not considered a filter that would typically be clogged.
Actually.... it wouldn't even be found in air handler. It's used for tankless water heaters.

See link below. They filter or trap bugs and other creatures from entering interior/room air stream.

On window AC's some drains have a pinched rubber tube for that function. Most occupants have probably never seen one.

The main function of a trap is to allow drainage when the evaporator is in a negative section of the air handler. Not as a filter.
You have to remember that the cold water draining through a dark space promotes growth. So it’s not about filtering out what could be in the condensate, it’s about preventing growth do to the condensate.
I think instead of trying to prove something here, the OP should go back to their HOA and ask them to clarify the letter. Because a condensate filter doesn’t exist in a normal hvac system.
