5 inch filter for 1 inch filter housing

[HydroAirJoe]

I've seen these somewhere in the past. Its a 4 or 5 inch deep filter than can fit in a standard 1 inch filter housing. IIRC the flange is 1 inch and you need clearance in the housing for it. Anybody have a link?

Maybe it's just me, but I'm picturing you pouring 5 gallons of water into a 1 gallon jar:eek2:

I am just not picturing how a 4-5" filter can fit in a 1" slot.

Hey robo don't you know its compressed and you slide it in the slot and pull a string and it expands out another 4 inches inside the return duct.:eek2::bump: Yeah that is wild. Like to see it.

Its not magical at all.....Honeywell makes them and they work amazing. If your return box is deep enough to let the filter fit inside the frame. They last 9-12 months in most cases. And even filthy still outperform those restricive 1" pleated from lowes

Thanks, exactly what I remember.

Same here he did say filter housing not return grill filter.:anyone:

[qwerty hvac]

Most of our systems here have the air cleaner at the furnace so that is why I thought of the boot first. I have seen these filters in some commercial setups though.

[SBKold]

The rest of the return goes unfiltered on most residential homes?

About 10% or so around here use a return filter grill. If you say filter housing I think of the 1" slot at the inlet to the furnace.

I guess if You think about it yes. We usually have the filters in the return drop of the furnace. Most of our units are in the basement so the return drops to the furnace. Usually in the well designed systems there is a return in every room so it is not feasible to have that many filters.

[SBKold]

Yes i can see that. They do that around here as well if its a low bid job. Its code to have a return in every bedroom so they would do a Media filter at the unit . The only thing is how nasty that duct gets.

[qwerty hvac]

Do you use a lot of duct board down there? We use a 100% sheet metal so a new install takes a while to collect a lot of dirt in the return. The supply's stay pretty clean especially if you seal the return after the filter.

[SBKold]

Yeah we dont have basements. So its mostly spider systems or a metal trunk in attics (scorching 75%) the other is under house in crawl space (no fun either!).

I hate crawl spaces. But I do like warm temps. I can hand you your tools while you are under there. LOL!!

[SBKold]

And probably fab me up some killer transitions and metal work to boot!

I do run a pretty good box and pan break if I do say so myself!LOL!!!:troll2:

That's what I was thinking too. They make sense for filter grills. Then again, most filter grills are undersized because contractors don't take into consideration the combined reduction of square area due to the grill "and" the filter. Most contractors size them to the grill without consideration for the filter restriction.

[SBKold]

I really try to upsell these based on that.

Those filters are nice but they do seem a little pricey. I also agree with the returns sized to small. Customer complains why are they so loud?

[SBKold]

They last 12months though and will save you at least thier cost in electricity as I believe they outperform a ordinary cheap 1" pleated even at the end of its life - - - if your unit is performing proper to begin with. Unless a customer is a religious filter changer they will benefit.

Yes I always recommend a pleated filter be installed. At least a 2" if not the 5" Aprilair.

They even make you do returns in every bedroom on high velocity systems and in retrofits?

[mchild]

I have been using the 20x30 ones for a couple of years now and they are great. Can find them at better price points than the link posted. Honeywell makes them in 17 different sizes and two different MERV ratings 10 & 8 (depending on the size).

I have run a strip of tape backed foam around the lip of the filter grill so they seat against the foam and have a better seal. Otherwise, I have noticed if they aren't seated just right you can get a fair amount of leakage around the back side. Change them once a year.

[SBKold]

No, thank goodness its just new construction. And to be honest Ive only seen one high velocity system actually installed around here. Im sure there are more but their rarer than rare.
