Minimum efficiency reporting value

Mine, for example, at my house is 16 by 20 by one.

If I go out and buy a HEPA filter, let's say a MERV 14 through 16 filter and throw it in there, I will effectively restrict the airflow to the point at which condensation will start becoming generated more so than the system can actually get rid of and I can actually cause downstream problems to that system.

So figure out exactly what is the top MERV filter that your system can handle before it starts to cause problems.

For most people, that's somewhere between MERV 8 and MERV 11 if you don't have a dedicated box.

For...

As far as like prevention methodologies, I mean, having it worked on periodically, I think is also really helpful.

I have one quick question too.

Um, well too, should I, is it okay to get your, uh, vents clean now from summer to fall? Has someone come out? And the second question is, what is the MERV number on a furnace filter? Mine's a small bungalow on the southwest side of Chicago on Garfield Ridge.

Is it the lower the MERV, the better? No.

The higher the MERV rating, the more particulate it blocks, okay? And it's a balancing act, right? So I highly recommend that everybody uses pleated filters because that is going to give you a much better air filtration rather than just the standard spun fiberglass.

But you're looking, on average, in my opinion, unless you're an asthmatic and you've got breathing issues, anywhere from a 10 to a 13 MERV rating.

And change them during the winter months once a month.

Yes.

you can find now.

Because of the other shit, that high MERV, any MERV rating, that shit puts a drain on your system.

For the same sucker?

Yeah.

They do HVAC filters.

So they have a comparison on their website, not their brand versus another brand, but they're just comparing a MERV filter versus a HEPA filter, right? And they have that knowledge.

And I think for LLMs, another layer of discovery is it's more top of the funnel, but if you want to be cited and influence an LLM answer, when someone's not quite ready to buy from your brand yet, these types of guides are a good way to get there.

And we've done them for SEO for forever, but I think now they have new meaning with LLMs, just from the research that I've done.

Yeah.

And then what sort of MERV level are you going towards? I was sort of curious about like how do you think of MERV levels? I was asking Bill that at lunch.

I was like how do you think of MERV levels in relation to microparticles or like is that calibrated per client or is that like you have sort of like here's my go-to?

Another reason why I like the Aprilaire is because I can get the same box and you can buy different MERV ratings for the filter.

So as long as it's large enough, physically large enough for the MERV 16, like it'll work with MERV 13, MERV 11.

They have 11 too.

I don't think they have 8.

like,

And so we use those.

They've got an amazing portable HEPA three-stage filtration HEPA air filter that's First stage is MERV 13 pre-filter.

The second stage is three and a half pounds of carbon to absorb chemicals and VOCs.

And then the third stage is a true HEPA.

And hence, they still are lingering around in the indoor air.

On the other hand, if we could replace an existing filter in an air conditioning system with a better filter, we go by the rating called MERV, minimum efficiency reporting value.

And that is an indication of how effective the filters are in capturing small particles.

So I would say that any filter with a MERV rating of 13 on and above So it's very effective in capturing small particles.

So if we do have an air conditioning system, but don't have access to an air purifier, the best solution is to install a filter with a MERV rating of 13 or above.

And when air purifiers come back in stock, what should I be looking out for? Are all air purifiers built the same way?

Not necessarily true.
