Best Carbon Filter for weed 2020 : Buying Guide

When you want to purchase a best carbon filter, there are some factors that you should consider. Here are some things that you should look for in a carbon filter:

  1. The number of carbon matter

When activated carbon is used, it can adsorb to the surface. When the coal has been fully adsorbed, it loses the ability to adsorb impurities. Therefore, ensure that you consider the amount of odor that is being produced so that you can know the amount of carbon to be found in the filter. This is critical because the amount of impurities being adsorbed can lender the filter useless within a short time.

  1. Durability 

Consider the longevity of the filter you intend to buy. Some filter brands in the market are cheap, and that wear out quickly. It is advisable to go for a high quality filter that will serve you longer. Remember, high quality products are more expensive compared to cheap products, but they are worth every extra penny you spend on them.

  1. The thickness of carbon matter 

A thick carbon filter is better. This is because the odor will have longer contact time with the filter increasing the chances of the odor being adsorbed. On the other hand, thin carbon filters are not effective in removing impurities because there is less contact time.

  1. Portability 

This factor is crucial because it determines how quickly you can move the filter. It is advisable to go for a filter that has a compact design. Compact filters besides being portable, they are also very useful in their work, and they have lower vibrations and produce less noise.

  1. Activated carbon 

A filter that uses activated carbon is cleaner as compared to those that do not use activated carbon. The cleaner the filter, the higher the life expectancy.

Also, depending on the activated carbon used, they come with different pore sizes. The major pore sizes available include: macro, meso, and micro-pores.

  1. Presence of pre-filters

The presence of pre-filter is critical because it helps to reduce the number of impurities that get into the air filter. The pre-filter helps to remove dust particles.

The pre-filter helps to keep the fan and the inline part of the filter in check. Besides that, it helps to increase the life span of the filter.

  1. Price 

Most people will be tempted to go for cheap products. But cheap is expensive as it were. Do not compromise on the performance of the product in order to go easy on your wallet. As much as it is crucial to consider the price, go for a high quality filter within your budget range.

  1. Versatility 

If you want a filter that gives you the best value for your money, then go for one that is multifunctional. If possible, choose a filter that works both as an air filter, an exhaust fan, or inline fan.

  1. Material used

It is paramount to consider the material used in the construction of the filter. This is critical not only for its durability but also for its functionality. High quality material might be costlier, but it will be worth your hard-earned money.

  1. Warranty 

If you want to have peace f mind, go for a filter with a warranty. While the warranty is in effect, you can be sure that in case of any defects, you have a guarantee of free maintenance. You will be sure that you are well covered, and it assures you of satisfaction.
