We want a product which is compatible with a large number of users as well as reasonable in price.

We trust the technology of RabbitAir. And the price is quite good for a part of the air purifier, too.

What Are Air Filters Available in the Market?

How can we come up with these five products above? It’s the result of studying different options in terms of materials and constructions.

Let’s overview different types on the market and do a fair-play evaluation of each.

1. Considering the Texture of Filters

Basic and HEPA

HEPA and traditional cores are the two most common types. More importantly, they all have lasted long on the market.

These filters, in general, are made of multiple layers of cloth such as foam, cotton, fiberglass, and so on. This multiple-layered filter helps with blocking dust and even micro-sized particles.

Let’s think about micro dust which causes respiratory illnesses. You cannot block them out of your house by shutting windows all days but using HEPA filters.

  • Advantages

Because basic and HEPA filters are quite useful and cheap, they become the consumer’s favorite. These parts are also easy to set up or clean if necessary.

  • Disadvantages

Only minus point is that users need to change the filter every month or two because they fill up with particulates very quickly.

Ionizers and Ozone Generators

While traditional filters only handle the air passively, people develop ionizers and ozone generator to solve floating particles.

This kind of filter will cause dust flying around to stick to surfaces. By doing so, it minimizes the effects of dust to people’s respiratory, especially children.

  • Advantages

This technology enhances air quality even better because it works actively to dust.

  • Disadvantages

However, the filters running on ionizing or ozone irritates lungs as well. Therefore, be careful when you choose these products.

  • Notes

In the market, we have electrostatic filters which work the same but cause less irritation.

Choose the right filter as your need
Choose the right filter as your need

Activated Carbon Filters

Apart from other filters, activated carbon filters cope with smells instead of particles.

You should now that bad smells also affect badly our respiratory. Ordinary cloth in filters cannot tackle intangible pollutants like smells but only dust or particles.

Will you use perfume spray to drown lousy smell? It is such a wrong solution that cause smell even worse.

Filters with activated carbon do not replace the smell by another. They neutralize the odor to make the room odorless.

  • Advantages

It is harmless to people’s health and irritation-free.

  • Disadvantages

Activated carbon filters need combining with other types because they cannot tackle particles.

UV Lights

We have filtrations to eliminate particles and odor, but microbes and viruses are existing in the house that mentioned filters could not remove.

Therefore, people develop UV lights in purifier to kills, harmful agents.

  • Advantages

It can deal with viruses and ultrafine particles, which is no kind of cloth can stop.

  • Disadvantages

These filters are only effective in a small area, so, people usually set it up nearby ventilators or windows where the air comes through before breaking into the house.

2. Considering Materials

Fiberglass filter

Fiberglass is a material commonly found in tradition or HEPA filters. It can stop dust and many sizes of particles easily.

It is so-called throwaway material because it only lasts about 30 days. That’s why we need to replace HEPA purifiers quite frequently.

  • Advantages

It is cheap material and easy to buy in any shops. And we consider it the reason why it becomes popular in the industry of making purifiers.

  • Disadvantages

However, it is not really effective in blocking allergens and microbes.

To freshen the air 100%, you need extra work from specifically functional materials.

Polyester and pleated filters

It is quite the same as fiberglass, but this material is elevated with better resistance and dust-blocking.

  • Advantages

They work better in trapping smaller particles in the air and more durable.

  • Disadvantages

They are more expensive than fiberglass

Washable air filters

  • Advantages

As its name, this material is washable.

  • Disadvantages

In fact, it works better and better with built-in dust. Washing it too frequently even reduces efficiency.

At last, we need to replace it, although it has longer life-span.

How to Change Air Filters?

Changing air filter is not a hard job. However, we need to follow step by step to set it correctly in the purifier.

Step 1: Identify Your Air Filter

It is crucial to identify the size and type of air filter you need to change.

If you don’t know exactly, you can ask local mechanics or shopkeepers referring to the model of air purifier you are using.

Besides, referring the machine, you can search on the Internet suitable replacement.

Step 2: Choose the Best Replacement

Sometimes, you might find out more than one option for replacement. Let’s make a wise choice.

First, pick the air filter with MERV (Minimum Efficiency Report Value) rating above 6.

The higher the rate is, the more effectively it stops small particles.

So, why don’t we choose the highest rate?

High MERV rate will run on more energy, that means you need to pay more for the bill.

Therefore, you should pick the one with the middle MERV.

Step 3: Locate the Air Filter Position

Each air purifier will have its own slot for air filters. Our job is to look for it.

Usually, we can find it in a box between the air handlers.

The part must be naturally removed so you can change the filter inside every month.

Step 4: Change the Filter

To make sure your safety, keep the purifier turned-off when you change the filter.

When dust and particles stop being trapped by the machine, you can remove the old filter.

If you find the correct place, the filter cover will be taken off smoothly.

Be careful with a dirty filter.

Throwaway old filter and insert the new one. Make sure that you keep the previous airflow when changing the original part.

Step 5: Check the Replacement

The best way to check if new part work is by running the machine.

If you do not hear any weird sound, it properly runs well.

You should clean off dirt around the ventilator to keep the new part out of dust.

Step 6: Take Note of the Date

Depending on the air filter, life-span varies. Therefore, it’s necessary to take note the date of changing. You know, to keep track.

We recommend taking a look at the filter every month to ensure normal operation.


Buying a replaceable air filter has nothing to say, but, you need to invest seriously in picking the best ones.

There are many choices available. Manufacturers are on the way to perfect their products by improving materials and technologies.

In general, the best air filters must be the ones which can handle different pollutants as suggested.
