my 97 lx sedan does not have the slot for the cabin air filter to be placed in my air box. and my car does have AC in it also. I guess this mod only works for certain civics in this generation.

Good info.

i have a 98 civic and it did not come with the in cabin air filter. Is there a how-to for the people who do not have the filter and want to clean that area?

ekhatchey

ok one quick question can u use the housing from the 98 and newer in place of the older one with out replacing the old core the reason im asking is i got the newer one but the core is damaged there is a big hole in one of the pieces of piping and i know mine works great but i want to put this but i dont know if it will work

^XpLiCiTxX^

how often should this be done. i have a 97, with 230k on it. prolly should be done now that its brought to my attention. lol

This is probably a dumb question, but what are the dimensions for the filter? I want to see if maybe something could be rigged up for the 5th gen. I have an evaporator and blower motor sitting around, so I can experiment and maybe figure something out.

If you just want to filter out large debris, you could use that like 1/4in thick filter used on window mount air conditioners. It flows pretty well and catches a little dust. Otherwise people are using HEPA vacuum filters or furnace filters on other vehicles.

Technically, this is correct - the diagrams don't show a filter - but only because they were optional.

The pollen filter on 5th Generation Civics in Europe was part number 08000-sr3-00EH. Don't check your EDM parts database at home - for some reason it doesn't list many of the optional parts for 5th Gen's.

Try www.lings.com instead. It will list the item as "POL.FILTER CIVIC 92".

Unfortunately, this is all the information I have at this time, including no information on what USDM or CDM filter assembly would be an equivalent OEM substitute.

Possibly worth trying is a part number 79831-ST3-E01 (filter) and 79832-ST3-E01 (frame). Though it is designed for the 5th Generation EDM Fastback and Aerodeck models, some sites list this as a fitment for a 5th Generation Hatchback and Sedan, also. Might be worth checking out. The size of this filter is L:~211.5-213mm W:~210-211mm H:~29.5-30mm; you could measure the dimensions of the duct near the blower to see if it will fit.

If your car is originally from the United States then it does not have this filter. Don't worry about having a dirty filter in there since there never was on.

And that goes for all the cars sold for the US market (they were built in the US, Canada and Japan).
08000-SR3-00EH is for the cars that did not come with air conditioning.

Unfortunately, 08000-SR3-00EH is no longer available through Honda. It has been discontinued.

Something interesting though:

The Insight apparently has TWO filters.

(Under HEATER BLOWER):


14 = 79831-S04-003 (ELEMENT, FILTER)
15 = 79832-S04-003 (FRAME, FILTER)
16 = 79833-S04-003 (SEAL)

And... (the one which is the same as the '98-'00 Civic and the CR-V)

(Under COOLING UNIT):


19 = 80291-ST3-E01 (ELEMENT, FILTER)
31 = 80292-ST3-E01 (FRAME, FILER - This is the CR-V number, because the frame is not available separately through the Insight listing)
20 = 80293-ST3-E01 (SEAL)

So the Insight has both an air conditioning filter, which fits in the first gen CR-V and '98-'00 Civics and then a heater filter.

So will the heater filter fit in a fifth gen or other model?

Anyone willing to give it a try? I'd suggest you look behind your glove box first. The built in filter is supposed to be a black box there.

JarvisW

I wish my Sol had a cabin filter.

NOFX

If you don't have air conditioning then your del Sol might be able to have a cabin air filter too.

Look at the post above yours. The information about fifth gens is the same for the del Sol. In fact, the filter part number DeSchlong posted is the same for the del Sol. That filter has been discontinued though, so we will need to find another filter that can work.

JarvisW

Ah, thanks, but I live in Texas, and MUST have A/C, so looks like I'm SOL (pun intended) unless there is some way to mod one between the condenser and fan, or heater box...

I probably wont be able to change it, unless I remove the condenser, so I donno.

NOFX

You're really going to have to remove the glove box and look back there.

I don't know what it looks like back there. See if there is a place for one.

Interesting stuff. I think we're almost there.

For starters: Unfortunately, there aren't two filters on the Insight. The evaporator and surrounding casing on a vehicle with A/C will take the place of where the Heater Duct is mounted. The diagrams should instead be interpreted separately, where the Cabin Filter assembly 79830-S04-003 is installed in the Heater Duct in a vehicle without A/C, and the Cabin Filter assembly 80290-ST3-E01 is installed in a vehicle with A/C.

To verify this, note that on a Honda Insight with A/C, under the HEATER BLOWER diagram, you cannot select No. 13 = 79810-ST3-G21 (DUCT, HEATER) nor No. 11 = 79830-S04-003 (FILTER ASSY., HEATER).

Neither of those filters will fit the 5th Generation Civic directly. This includes delSols as they share (mostly) the same heater assembly part numbers. Photos taken from my non-A/C 1994 Civic EH2 are shown in Figure 1. Note that there is no place to put in a filter. I don't even know where the EDM optional 08000-SR3-00EH Cabin "Pollen Filter" for non-A/C 5th Gen Civics would have gone, unless it mounts inside the duct either on the left (most likely) or right hand side. But, it's really a moot point because Honda doesn't even make them anymore and they are impossible to get.


So, how to resolve this? Hopefully, you can follow the bouncing ball. I will try to be as clear as I can, and I am starting with non-A/C Civics. First let's have a look at the 6th Generation Civics.

Examining the EDM parts diagrams, it looks like most or all trim levels of non-A/C EDM 6th Generation Civics came with a filter in its Heater Duct.

For example, the relevant part numbers in an EDM German 1996-2000 Civic 1.4i or VTi 3-dr Hatchback are listed below the parts diagram in Figure 2:
Figure 2. EDM "HEATER BLOWER" parts diagram for German 1996-2000 Honda Civic 1.4i or VTi 3-dr Hatchback. Note Cabin Filter assembly and larger Heater Duct.

8 = 79810-ST3-G01 (DUCT, HEATER)
10 = 79830-S04-003 (FILTER ASSY., HEATER), consisting of
--11 = 79831-S04-003 (ELEMENT, FILTER)
--12 = 79832-S04-003 (FRAME, FILTER)
--22 = 79833-S04-003 (SEAL, FILTER)

However, as mentioned, non-A/C CDM/USDM 6th Generation Civics also did not come with a filter in the Heater Duct, and thus received a different part.

For example, the Heater Duct part number in a USDM 1996-2000 Civic CX 3-dr Hatchback is listed below the parts diagram in Figure 3:
Figure 3. USDM "HEATER BLOWER" parts diagram for 1996-2000 Honda Civic CX 3-dr Hatchback. Note no Cabin Filter assembly and different Heater Duct.

7 = 79810-SR3-A01 (DUCT, HEATER)

And of course, as we know, non-A/C CDM/USDM 5th Generation Civics also did not come with a filter in the heater duct.

For example, the Heater Duct part number in a USDM 1992-1995 Civic CX 3-dr Hatchback is listed below the parts diagram in Figure 4:
Figure 4. USDM "HEATER BLOWER" parts diagram for 1992-1995 Honda Civic CX 3-dr Hatchback. Note no Cabin Filter assembly (no markets came with one
as standard equipment) and Heater Duct.

8 = 79810-SR3-A01 (DUCT, HEATER)

Hopefully, you see where I'm going with this. At this point, note that:

1. All things being equal, the 6th Generation EDM Civic Heater Duct part number 79810-ST3-G01 (or its equivalent) should retrofit exactly into a 6th Generation USDM/CDM Civic as a substitute for 79810-SR3-A01, giving you the ability to add a cabin air filter. This should be good news for many of you.
2. Part number 79810-SR3-A01 for the 6th Generation USDM Civic is the exact same part number for the Heater Duct as in a 5th Generation non-A/C CDM/USDM/EDM Civic.
3. Logically, it follows that the 6th Generation EDM Civic part number 79810-ST3-G01 (or its equivalent) should also retrofit exactly into a 5th Generation CDM/USDM Civic as a substitute for 79810-SR3-A01, giving you the ability to add a cabin air filter! There should not be any obstructions to installing this larger piece; I base this on the fact that the duct area is designed large enough to fit the much-larger evaporator and casing on A/C-equipped vehicles.

The question remains, though, where to find 79810-ST3-G01? This Heater Duct is installed on the following vehicles (all LHD):

EDM

• 1995-2000 Civic 5-dr Fastback
• 1998-2000 Civic 5-dr Aerodeck

• 1996-2000 Civic 3-dr Hatchback
• 1996-2000 Civic 4-dr Sedan
• 1996-2000 Civic 2-dr Coupe

• 1997-2001 CR-V 5-dr

• 1998-2000 Integra 3-dr
• 1998-2000 Integra 4-dr
  • NB: This generation Integra was only available in Europe for 1998-2000, I believe.

USDM

• 1998-1999 Acura Integra RS 3-dr
  • NB: The RS model was discontinued after 2000(?).

So, this leaves rather limited choice if you're headed to the salvage yard: one model of Integra in the base RS trim level during two model years! You're totally hooped if you're in Canada, where Integras weren't sold after 1998, if I recall correctly. If you don't feel like wasting your time hunting through yards, you could order a brand new heater duct - but at about $90, you're likely liable for severe sticker shock.

Of course, the Heater Duct that you pull from the Integra (or ordered) won't have a cabin filter either, but it *should* have the slot for one. The Heater Duct Cabin Filter, as mentioned in the earlier posting by NOFX, can be ordered brand new using the part numbers from a Honda Insight, as these are the exact same as for the non-A/C EDM 6th Generation Civic.

There is another possible option. Part number 79810-ST3-G21 is shown on the European parts diagram for the 1995-2000 5-dr Civic Fastback & Aerodeck as an alternative to 79810-ST3-G01 (ie., both parts are listed). This suggests that both parts are interchangeable. Part number 79810-ST3-G21 is also listed as the Heater Duct on the EDM & USDM Honda Insight. While there is only the remotest of possibilities of finding an Insight at a salvage yard, they are available brand new through a Honda dealer at the more affordable cost of about $40.

MORE TO COME.
Next up: Is a Cabin Filter retrofit possible in A/C-equipped 5th Generation Civic?

NOFX

I mean both filters are available on US Insight models. Meaning we can probably still get both brand new from Honda.

Whether they both come on the same exact specific vehicle means nothing really.

I only have read that the filter for del Sols (without A/C) goes in a black box behind the glovebox.

I would possibly request European owners to look to see if they have the filter or such and see if they are willing to take some measurements. Plenty of cars use cabin air filters, so I don't think it's out of the realm of possibility that we can find one that will fit.

I'm going to have to cut myself short of the specifics you go into after that because I'm getting ready for work and well, ADD is in full power (so much of what you typed is a blur of words that I can't remember once I finish the sentence).

I'll try to get back later tonight or better yet tomorrow afternoon.

NOTE:

I ordered the cabin filter frame and it did not come with the foam lining - I don't know if this is necessary but make sure you add one.

I figure I've threadjacked enough. I posted a DIY in its own thread here: How-To DIY: Cabin Air Filter retrofit for certain 92-95 / delSol / 96-00 Civic models , where I can be either heralded as a saviour or widely discredited.

awesome write up

just ordered my parts, so cant wait to get it installed

SWEET, sweet, SWEET write up!!

Finally got my parts & the install was super simple!

cant wait to get in & drive it to see how it "works" LOL
