AirDoctor 3500 vs. Hathaspace HSP002 Air Purifier Design Comparison

AirDoctor 3000 vs Hathaspace HSP002 Air Purifier Review

Air Doctor 3500

AirDoctor 3500 is extremely popular for its compact, beautiful, modern construction and design. You will be amazed by the colors of these air purifiers that brilliantly suit all kinds of decor.

These fit your surroundings and don’t look out of place. The manufacturers construct these air purifiers to be unique and distinguishable. The corners of the air purifier are more rounded and look classy.

Hathaspace HSP002

The Hathaspace HSP002 air purifier also has a modern and sleek design. These are smart purifiers and can intake air from all sides.

These suck in the unfiltered air, and then the air passes through the filtration system. After the air is cleaned and filtered by the system, the clean air is distributed all around the room.

In addition, these air purifiers are light in weight, and the base is wide, which gives them more stability.

You will get a touchscreen panel with six controls on the top of a Hathaspace HSP002. The display will also show you the air quality score and the touch controls.

These air purifiers are built with three fans to spread cleaner air to every corner of the room.

AirDoctor 3500 vs. Hathaspace HSP002 Air Purifier – Functionality

Every air purifier more or less does the same type of work; they clean the air.

However, these are built using different technologies and have different processes of filtration that they use to clean the air and make it fit for breathing.

Air Doctor 3500

In AirDoctor 3500, you will get an UltraHEPA filtering system. UltraHEPA filtration differs from the normal HEPA filtration system in ordinary air purifiers.

This technology cleans the air in the best way possible. It is so powerful that it kills and eliminates pathogens and other pollutants that are 0.003 microns in size.

AirDoctor air purifiers have a four-stage filtration system that cleans the air inside your room faster and makes it safe for adults and kids.

Another thing that one cannot neglect is the pre-filter filtration system. This system captures larger particles and is easy to clean. These can be washed as well and reused without any trouble.

Hathaspace HSP002

Let’s talk about the functionality of the Hathaspace HSP002 Air purifier.

It has a five-stage filtration process and has excellent performers based on the quantity and quality of the air filters inside.

Hathaspace HSP002 is safe to use and is certified. These also have an ionizer that kills pathogens and viruses and protects your house’s air.

The mechanical filters used in these air purifiers are 100% ozone-free as well.

How Do They Work?

Air Doctor 3500

The Air Doctor 3500 air purifiers follow the pro-filtration process. The pro-filtration process has four main steps.

These four steps help clean the air faster and easier. The four steps of filtration that occur are below:

Air Doctor 3000 Air Purifier Filters Review

  • The first step in the pro-filtration process is removing large particles from the air, such as dust, dirt, pollen, pet hair, and much more. The pre-filter does this.

The large particles get trapped when air passes from this filter, and the rest goes to the next step. These pre-filters are reusable and can be washed when they are filthy. They need to be cleaned so that the air filtration doesn’t stop.

The small particles with 0.003 microns are collected in this filter, and the air is filtered. These filters are efficient and kill 99.95% of bacteria and airborne viruses.

  • The third stage is the activated carbon filter. You will get the dual-action Carbon, gas, and VOC filters that make the air cleaner and safer in this filter.
  • Finally, the fourth stage has the ionizers. This is one of the best cleaning features found in AirDoctor 3500. In this system, the air is passed through a negatively charged ion that removes odor and other kinds of smell from the air and helps you get cleaner and fresh air in your house.

Hathaspace HSP002

The Hathaspace HSP002 Air purifier has a five-stage purification system. These are effective in removing all kinds of air pollutants that you want to remove.

Following are the steps you will see in this air purifier.

Hathaspace HSP002 Air Purifier Five Stage Filters

  • Pre-filters are the first stage that removes larger air pollutants like mold, pollen, hair, spores, pet dander, etc.
  • Next comes the cellular-activated carbon filter. This filter absorbs and removes all the gaseous pollutants in the air. These gas pollutants can be smoke, odor, VOCs, and smell.
  • The third is the antibacterial filter that most air purifiers do not have. This filter mostly targets germs and bacteria and cleans the air.
  • The fourth stage is the true HEPA filter. This is one of the essential filters that help remove small particles and pollutants of 0.3 microns in size.
  • Finally comes the ionizers. This filter cleans all the remaining air pollutants from the air.

Air Doctor 3500 vs. Hathaspace HSP002 Air Purifier – Features

AirDoctor 3500

The Air Doctor 3500 air purifier has an amazing list of features that make it popular among people. Some of the features are as follows:

  • AirDoctor 3500 has a timer that helps you turn off the unit when the work is done. This is efficient for forgetful people who easily forget to switch it off after one to two hours of use.
  • The next fascinating thing in these air purifiers is the sensors that help you learn about the air quality inside the room. These gave different colored lights that show you the quality of the air; for example, orange shows that the air is moderate, red shows that it is poor, and blue shows that the air is good.
  • One can also change and regulate the speed of the fan. There are three modes: low, medium, and high.
  • The Automatic mode helps the air purifier to perform all its duties alone.
  • The most amazing feature is the filter change alter, which helps you learn when to change the filters and clean them so that the air purifier can perform its duty in the best way possible.

The updated version of AD3500 – the new AD3500i model- also has a WiFi-connected app, making it a more modern air purifier.
