Commonly asked questions the first time someone learns about Hood & Filter.

I just learned about Hood & Filter but know little about it. Can you tell me in a nutshell how it works?

The design of Hood & Filter is that you clean the filters with virtually no time or labor, by spraying the filters once a night while the filters are in place. This cleans the filters. Once a week you pull the filters down to rinse them. No overnight soaking is needed. No scrubbing or scrouring is needed. The grease will fall right off to the bare metal.

While you are applying H&F once a night, the entire system is being cleaned as well. With the vent hood on and pulling air, roughly half the product stays on the filters and the other half goes into the system. In the exact same way as your grease does.

Hood & Filter’s weight is lighter than grease. The grease is pulled into the vent hood by the exhaust fan. So is Hood & Filter. And since H&F is atomized and is lighter than grease, it will get to the same places within the system that grease gets to, whether its the fan blades, a 30 foot horizontal run of duct work, or six stories straight up to the roof. If grease can reach these places, so will Hood & Filter. And that is all it takes.

What about the quarterly inspection?

Vent hood inspections, whether quarterly or otherwise, are always required regardless of the cleaning method.

Most customers schedule these for themselves, normally using the same company they have used in the past to clean their hoods, but now hiring them to inspect them.

If you need, we can contract someone to do it for you for a fee.

I have a lot of young employees. What if they forget to apply it sometimes?

Forgetting to apply the product from time to time will not adversely affect H&F’s results. It will still clean the entire system. Sometimes in the first couple of weeks they may forget from time to time. The product is very ‘forgiving’ in that it has the ability to make up for missed days.

We want you to apply it daily, of course. That gets the best results. But employees forgetting to apply it sometimes is okay.

How can the whole system get clean just by spraying the filters?

Excellent question. The best way to explain how Hood & Filter can clean your entire system just by spraying your filters, is to first explain how your system gets dirty.

Small, atomized particles of grease go airborne from the grills and fryers while cooking during the day. The exhaust fan pulls that grease into and through the filter panels. Whatever grease isn’t caught by the filters gets deposited somewhere inside the system.

When you are applying Hood & Filter as a fine mist, the vent hood is on and pulling air just as it is when you are cooking. The product is lighter than grease and is being sprayed in fine particles. Hood & Filter will travel in the same way grease travels throughout the system to any and every place that grease goes. It will get to the exhaust fan, to long horizontal runs of duct work, and even to the top of systems that are several stories high. If the system is able to pull grease there, it will pull Hood & Filter there as well. And that is all it takes.

We get heavy grease buildup on our filters in less than a week and they are quite difficult to clean. How can all of the labor of cleaning filters be eliminated just by spraying the filters?

Hood & Filter is continually breaking the grease down when it comes in contact with it. The new grease added on during the day never gets a chance to harden and become sticky, nor does it get a chance to build up. By the time you get to the end of a week when you would normally have a lot of work to do to clean your filters (or pay someone else to do it for you), now all you have to do is rinse the filters.

As you see in our videos, the grease falls right off to the bare metal. No matter what type of grease you have or the volume of grease you make, Hood & Filter always gives the same bare metal results.

As an added bonus, when you go to rinse your filters after applying Hood & Filter over the course of a week, 90% of the grease is already gone before the filter gets to the sink. Your older way of cleaning filters, whatever way that may have been, when you went to clean your filters… all of that week’s grease is on the filter when you clean it off. When you use Hood & Filter, at least 90% of that grease was eliminated while the filters were still in your vent hood system. That means all of that grease is not going into your drains and grease trap.

That’s great for the drains, great for the grease trap, great for the city sewer systems and great for the environment.

Sounds too good to be true. It can't possibly be that easy and get bare metal clean results across all restaurant types.

We hear that quite a bit, and its easy to understand why. Hood & Filter reinvents everything about hood and filter cleaning.

What used to take a cleaning crew with pressure washers a couple of hours to do has now been reduced to simply spraying your filter panels once a night for 30 seconds.

And now the hood is clean every day, not just once a quarter. So yes, we get that comment quite often… for good reason.

Your instructions say the product should be applied as a fine mist. Won't it work better to spray it as a stream since it will reach further into the system?

Hood & Filter should always be applied as a fine mist. Never apply it as a stream. When you are applying, you want the coverage that a fine mist will give over the filter panel’s surface.

Secondly, you want the system to be able to carry the product all the way to the roof. To do that, H&F needs to be atomized, like a fine mist. That way it gets to any and all places that the system pulls grease into.

If our hood has a good amount of grease buildup inside, should we wait before starting with Hood & Filter?

No, it is fine to start with Hood & Filter at any given time in your inspection schedule.

Let’s say that you get inspected once a quarter and you are due for another inspection in two weeks (meaning its been almost 3 months since your last cleaning). Can you begin Hood & Filter that close to an inspection? Of course! You will get immediate benefit on the filters, no matter how much grease is up inside the system.

Is there benefit inside the system with the inspection being so close? Yes, but it depends on how close the inspection is and how much grease is present. Let us give you an example. Even in a short time frame such as two weeks with a good amount of grease inside the system, Hood & Filter can accomplish a good amount of reduction in a short period of time. Can it get bare metal clean in two weeks with a really greasy hood? Likely not, you only have two weeks to eliminate almost 3 months of grease. But the amount of grease inside the system will be reduced, and it could get you a lower than normal quote for cleaning it. Just depends on the amount of grease buildup and the amount of time left until the inspection.

So to answer the question, a new customer should start on Hood & Filter regardless where they are at in their inspection schedule.

We started a week ago and noticed that we are emptying our drip pans more often than before. Is this normal?

Yes. This is very normal when there is grease buildup inside the system when Hood & Filter is started, although very temporary. This ‘extra grease’ in the drip pans only happens for the first two or three weeks, then it returns to normal. What is happening is that the Particle reduction process is breaking down the grease buildup so rapidly that gravity draws some of it down to the drip pans.

But again, this only takes place in the first two or three weeks and then returns to normal.

Note of interest – if you would like to experience this process in a slightly different way, you can try this when you take the drip pan down to empty the grease into its appropriate disposal location. (Before doing this make sure you have the following: 1. Management approval and, 2. Make sure the grease in the drip pan isn’t hot – don’t want someone burning themselves). After getting management approval and making certain the grease isn’t too hot to touch, you can take your thumb and index finger and rub some of that grease in between your two fingers so that you can feel its consistency. You will notice that the grease feels very ‘watery’, not at all like grease normally feels (a thicker, sticky consistency, much like molasses). This shows you what happens during the Particle reduction process. Much of the molecular and atomic structure of the grease has been eliminated, so even though it looks like grease… much of what ‘makes it grease’ has been eliminated. Many new customers like doing this since it lets them better see, if you will, what exactly is going on.

Is Hood & Filter safe?

From a chemistry standpoint, Hood & Filter is as safe as it gets. It is food safe, non-toxic, non-hazardous, and non-corrosive; as well as having a neutral pH and is fully biodegradable. Hood & Filter is safe on all surface and material types including plastic and rubber along with all types of metal, including aluminum and stainless steel.

Do you have to start off with a clean hood?

No. Starting with a clean hood works well, obviously. But it is definitely not necessary. Remember that you are not just cleaning the inside of your system, you are first cleaning the filters themselves. Hood & Filter gives immediate benefit to both the filters as well as the entire system. If you start with a clean hood, one that was very recently pressure washer cleaned, Hood & Filter will simply be keeping the hood bare metal clean. It is eliminating all of the new grease that the system is bringing in every day.

Pressure Washer Cleaning

Cleans only once every 3 months

Traditional hood cleaning means the system is only clean four times a year.

Cleaning filters is additional

To keep filters clean on a regular basis is an added service, such as soak tanks or filter exchange.

Grease builds up everyday

Grease builds up inside system every day. Increases fire hazard. Reduces system’s performance.

Fire Safety

#1 reason for hood cleaning is fire safety. But the system is only cleaned once a quarter.

 

Hood & Filter

Bare metal clean everyday

Hood & Filter keeps the entire system bare metal clean every single day.

Cleans filters everyday

It’s recommended that filters should be cleaned at least once a week. Now they are clean every day.

Grease is eliminated everyday

Grease never builds up in the system when using Hood & Filter. Never.

#1 in Fire Safety

System is bare metal clean 365 days a year.  From a fire safety standpoint, its untouchable.

The Simplicity of Hood & Filter

Simply Spray

Spray Hood & Filter once a night onto filters while they are in place and hood is on. Takes less than 30 seconds per hood. And that is all.

Entire Hood Is Cleaned

By spraying onto filters, it eliminates the grease to the bare metal every day. From the filters up and through the system to the exhaust fans.

Rinse Filters Once a Week

Simply rinse filters with hot water once a week. What little grease is left, it falls right off to the bare metal. No overnight soaking, no labor, no time and no mess.

Simple. Advanced. Game Changing.

Bare Metal Clean Everyday

Traditional pressure washer cleaning is unable to keep a vent hood system clean every day. A cleaning crew cannot come out once a night to clean your system. Hood & Filter cleans the system to the bare metal every single day. A six panel vent hood system takes less than 30 seconds a night.

Most Fire Safe Method of Cleaning

There are many reasons you have your kitchen exhaust system cleaned regularly, but the #1 reason is fire safety. What makes a system fire safe? A system that is bare metal clean every day of the year. Not just once a quarter. Hood & Filter keeps any vent hood system clean 365 days a year.

Complete Labor Free Filter Cleaning

Simply pull your filters down once a week and rinse them off with hot water. The grease falls off to the bare metal. Everywhere there is grease on your panel, it eliminates it. No more overnight soaking and no scrubbing. No soak tanks or filter exchange needed.

Simple. Thorough. Extremely Effective.

The ability to clean your entire vent hood system, from the filter panels to the roof, changes everything. Bare metal clean, 365 days a year, with absolutely no labor. All in the palm of your hand. Takes less than 30 seconds a night to clean an entire vent hood.
