Buying Guide Of Best Backpack Sprayer Under $100

If you want to do gardening in a proper way then having all the necessary equipment is a must. 

Among them, one of the most useful pieces of equipment is Sprayer.  A backpack sprayer is a compact and easy-to-use garden gear that is very useful to keep your garden safe from harmful insects.

How to Choose The Best Backpack Sprayer Under $100?

Not every sprayer is good for each Gardner. There are some key factors that must be understood before making a buying decision which are:

  • Pressure(PSI)

The term PSI stands for pounds per square inch and means how much pressure a backpack sprayer generates through its nozzle.

Normally an average PSI for a backpack sprayer is 70 psi. Some small models come with 40 psi pressure and a large one may use up to 150 psi. It totally depends on your need and the size of the garden. 

If your garden is small then there is no sense to buy a sprayer with more psi and in this case, a sprayer between the psi rating of 40 to 70 is enough for your need. 

If you are an owner of a large lawn with lots of hard-to-reach points then a sprayer of 70 psi or more will be right for you.

  • Tank

The capacity and the size of a tank depend on the size of the area where you want to spray. If you are not a professional then a sprayer with a capacity of 2 to 4 gallons is perfect for spraying a yard between 5000 to 10000 square feet.

The weight of the tank you feel heavy while it is full of pesticides or herbicides. 

  • Manual Pump or Motorized Pump

An internal pump is used to draw liquid outside of the tank. To operate this pump there is two procedure the first one is manual and the second one is by a motor.

In a manual way, a hand pump is used to draw liquid from the tank, which is attached to the backpack chamber. This procedure is useful only to spray in a small area. 

The hand-operated sprayer is not useful for a lawn because in this way hand mussels get tired. 

On the other hand, a motorized sprayer gets power from a battery or gas. A battery-powered sprayer is easy to set up and easy to use. Some best backpack sprayers for yards are operated on battery.

A battery-powered backpack sprayer costs around 150$ to 500$. The best backpack sprayer battery-powered is useful for a big project or long hours of spraying tasks.

  • Comfortability

The backpack sprayer comes with shoulder straps. In budget-oriented sprayers, you’ll see straps are not well padded but in some pricey sprayers well-padded straps are used even though you can see some kind of lumbar support in some models. 


A backpack sprayer is an easy-to-use and compact tool to tackle harmful insects and take care of your garden.
