Comparing Types of Disinfectant Sprayers


Disinfectant sprayers are quite a convenient cleaning solution when you want to get the job done quickly, without any delays or problems. All you have to do is simply spray them over the surface and allow the solution to do its magic.

When it comes to disinfectant sprayers, there are quite a few choices that you can go for – each with its own advantages and drawbacks. Understanding them will help you choose the best one, depending on your needs. In this article, you will learn exactly which sanitizing equipment works best for the establishment that you are attempting to clean.

Pump Sprayers and Spray Bottles

Pump sprayers and spray bottles are among the most popular ways to disinfect a surface, mostly because they are the most affordable options. Spray bottles are something that every homeowner has, and they represent an easy way of putting the solution on the contaminated surface. Practically, all you have to do is press the sprayer nozzle and allow the substance to fall on the desk, the chairs, the handles, or any other surface that you might want to have cleaned.

Pump sprayers are also a convenient solution. They are also a kind of spray bottle that requires some manual operation, but they don’t give you the cramped trigger finger syndrome. These sprayers are convenient as you can treat a larger area.

Advantages

Spray bottles and pump sprayers have quite a few advantages – but perhaps their main perk is the fact that they come at a low price. This makes them a good money-saving solution if you need to cover a bigger area. They also come with a simple design, so you will not have to go through any troublesome processes to use them. They are also some of the most accessible options, as you may easily buy a spray disinfectant bottle from your corner convenience store.

Drawbacks

One of the problems with spray bottles is that they have a slow manual process. While they might be a good solution to have in your home when protecting yourself against viruses such as COVID-19, they might not be such a good option if you want to disinfect a larger area.

Spray bottles also have quite an inconsistent coverage packed with drips and runs. So, if you wish to get good coverage, you might have to take a cloth and spread the solution yourself. Not only would this require additional steps to cover the area, but you also need to go the extra mile in order to clean it down.

Spray bottles and pump sprayers also have a small reservoir – which means that you will have to fill them more frequently. If you wish to finish the job quickly, this type of disinfecting equipment won’t allow you to do that.

Electrostatic Sprayers

The electrostatic disinfectant sprayer has been around for quite some time now, but the technology is still greatly appreciated by those working in the hygiene domain. An electrostatic sprayer is practically an air-assisted tool that creates tiny droplets that are 900 times smaller in comparison to the ones produced by a standard sprayer.

These small droplets are also given an electrical charge – one that leads to a natural force between the target surfaces and the spray droplets. Most of these surfaces are either neutral or negative.

To put it simply, just like a magnet pulls the metal pieces towards it, so does the target pull the droplets. These droplets would slowly become attracted to the surface as they get nearer, then reversing their direction and moving upwards against gravity when they get closer. This quite remarkable process would spray both backsides and undersides of the target, mostly being referred to as a “wraparound.”

Advantages

One of the main advantages of this type of disinfectant sprayer is that it offers good coverage even on complex surfaces. Unlike traditional sprayers, there should not be any “blind spots,” allowing you to get more coverage much quicker – and with less product used. While it is still in need of manual operation – meaning, you will have to carry it around and direct the wand through the room – the process is sped up, which results in reduced operator fatigue.

Drawbacks

Similar to standard spray bottles or pump sprayers, this type of disinfectant spray machine has a small reservoir – which means that you will have to fill it quite often. Even if you do get quite good coverage in comparison to standard sprayers, it will still lead to wasted time whenever you have to change it.

Since you will have to carefully spray the substance over the surface, the application process is still rather slow. This means that if you have to spray through a bigger establishment, it might take quite some time until you get the work done.

Electrostatic sprayers have a “one product fits all” type of application approach. This means that if your surface needs a different kind of attention, this sprayer cannot be customized to your needs.

The product type is mostly known for its “wrap” effect – but even in the most efficient products, there are limits to that effect. For contaminants that can live for a longer time on surfaces, such as the virus responsible for COVID-19, it might not “wrap” correctly around the surface, leaving the area still contaminated.

Last but not least, considering how limited their production is, the electrostatic disinfectant sprayer is also quite expensive. A good quality sprayer can easily cost well over $600 – particularly if you go for a large-capacity one (over 5 gallons). If you are planning to disinfect everything while sticking to a budget, you might not be able to adhere to your plans if you use this type of product.

Fogging Sprayers

You may clean every surface in a room – but if the air is packed with contaminants, then all that cleaning is for nothing once the virus falls onto the surface. What do you do in this case? The solution seems rather obvious: you clean the air.

When you use any kind of spray disinfecting equipment (e.g. spray bottle or electrostatic sprayers), you are bound to miss a few spots that could be harboring viruses and harmful microorganisms. Not to mention that with standard sprayers, you will be wasting quite a lot of time trying to disinfect a bigger building.

This is where fogging sprayers come into the mix, a type that divides into two more categories: wet and dry fog. Wet fogging sprayers generally use either hydrogen-peroxide bases or chlorine dioxide products, whereas dry fogging sprayer systems only use hydrogen-peroxide disinfectants to decontaminate the area. The disinfectant is sent straight into the air, killing the viruses while they are still airborne – preventing them from attaching to the surface.

Advantages

The reason why this type of sanitizing equipment is so convenient is that instead of targeting a smaller, set-on area, it creates a “fogging blanket.” It can cover your entire property – including the areas that you would normally not be able to get to with your standard disinfectant. This way, with a functional fogging sprayer that is used properly, you should be able to disperse extra-fine droplets that can kill viruses from your floor, walls, ceilings, and furniture.

It’s usually a gas-powered unit (you may go for electric fogging machines as well, although they are not as common), so it’s a good solution to ensure that you cover the entire area quickly. Plus, you may find it in a portable configuration – meaning that if you have multiple rooms to cover, it should be quite easy to take this around with you.

Drawbacks

While there are indeed some perks to using fogging sprayers, there are also some disadvantages that users need to keep in mind. For one, a fogging unit works by filling the air inside the room with disinfectant – which means you will be able to get more coverage much faster.

While the idea is right, you cannot ensure that you get proper and efficient coverage – like you would if you used a disinfectant spray bottle and a wipe. This is because a fogging simply sprays the disinfectant in the air, allowing it to fall randomly over the surface – in which case, some areas may be missed. Cloths can cover the whole surface, mostly because you are the one directly spreading it over that surface.

Plus, for a virus to be killed, the surface needs to be visibly wet with disinfectant for a certain amount of time – also referred to as dwelling time. When the sprayer sends the disinfectant in mist form, it risks drying out much sooner – which is why there is no guarantee that the dwelling time will be met.

The application process is still quite slow with this type of disinfectant spray machine. Granted, there will be less human input – but you will have to leave the fogging sprayer inside the room long enough for it to do its magic. Not to mention that after that, you will have to steer clear of the room for a while so that the air becomes breathable again.
