  • NOISE LEVEL: – Since you plan to use these gadgets 24/7 – it is better you opt for a silent unit. Some units can make some noise at the start because that is when they capture most of the dust but after a few seconds, the unit will tune its self to a low setting mode which is very silent and effective. Those with turbo settings are noisy but should only be used when the dust is too much.


  • ENERGY CONSUMPTION:- Opt for a model which is Energy start certified – these appliances are supposed to be used 24/7 so they have to be power friendly. You have to get cleaner air at a small fee.


  • MAINTENANCE COSTS:- By default all air purifiers need maintenance. You have to clean / replace filters. But buy a model which has HEPA filters, these last for long (2-3 years). Also make sure that those filters are available on the market so that when the need arises, you can easily get one. The life span of air filters is determined by the quality of air being filtered and how many times the unit is being used. People who leave is dusty areas might replace filters more than those leaving in cleaner areas.


  • COVERAGE AREA:- Opt for a model which covers a wide area – it should be in position to filter and clean air in a wide area. But if you have a small room, opt for a smaller unit like GermGuardian AC4825.


  • NO OZONE GENERATION:- Beware of models which generate ozone pollution – these are harmful to your health especially when you have asthma & allergies

CLEARING ODORS FOR PETS: – If you leave with pets (dogs/cats) there is one thing that you have to be sure of and that is; pet odor and dander that comes from dogs.

The table below shows 6 air purification stages that Air MinusA2 uses to make air in your room fresh, clean and safe.




(Stage 1)

It purpose is to trap and reduce large sized allergens, particles and dust that gets its way into the air you breathe. By doing so all these particles are eliminated from your air. The Pre-filter can be removed and washed. When it’s clean, less strain is put on the machine.
Medium Filter 

(Stage 2)

The main role of the Medium Filter is to capture and reduce on airborne particles that are larger than 1 micron. A good example of such particles includes; pet dander, pollen and mold.
BioGS HEPA Filter

This is the last stage of air purification. The Negative Ion Generator produces negative ions which fortifies the air you breathe. It will also freshen the air in your indoor environment


BioGS HEPA Filter vs. typical True HEPA Filter

Unlike traditional HEPA air purifiers which trap allergens and contaminants – that build up over time in the air purifier and affect its performance plus efficiency – Rabbit AirMinusA2 uses a BioGS HEPA filter – it also traps allergens but they don’t build up in the machine thus maintaining the performance of the machine (but at the same time prolong on the lifespan of the purifier)

 (1) Germ Defence filter (The main purpose of this filter is to effectively trap and reduce particles, airborne bacteria and mold spores that carry viruses with them). (2) Pet Allergy Filter (If you leave with pets, this is the best filter for you. It traps and reduces pet dander and related pet allergens that can make it hard for you to breath) (3) Toxin Absorber Filter (Just like its name – it deals with volatile toxic organic compounds and other related harmful chemicals – I recommend this type of filter to people who leave in highly polluted areas) (4) Odor Remover Filter (If you smoke or cook – this would be the best choice for you. It traps and reduces odors from cigarettes, cooking, mildew and pets. Your house will always smell fresh)

  • 3 STAGE FILTRATION SYSTEM:- Whirlpool AP51030K uses a three stage filtration system which is comprised of a carbon filter, pre-filter and a true HEP filter. Each of these filters captures and removes harmful particles in the air you breathe. For example, (1) The Pre-filter captures large particles thus prevent them from entering the unit. (2) However, some large particles might find their way inside the unit – these will be captured and removed by a carbon filter which also eliminates bad odors and protect the life of the HEPA filter. (3) Now at the heart of the Whirlpool Whispure 510 is where we find a true HEPA filter – this one provides maximum filtration of your room’s air by eliminating 99.97% of particles that are 0.3 microns and larger than that. Some of the particles that the HEPE filter deals with include; pollen, dust mites, mold spores, dander, ragweed and other microscopic irritants that can damage your indoor air quality and Worsen allergy and asthma symptoms.


  • REPLACING FILTERS:- If you run this unit for 24 hours a day in a turbo setting and at least 8 hours of sleep mode – you will need to replace carbon filters every after 4 months. For the sake of HEPA filter – you will replace it  after 1.5 years of usage. In terms of price ”Whirlpool 8171434K Large Air Purifier Carbon Pre-Filters, 4-Pack” and Whirlpool 1183054K HEPA Replacement Fits Whispure Air Purifier Models AP450 and AP510. Judging from these two maintenance costs – Whirlpool is worth the cost – it works well and it is affordable to buy & maintain.


  • NOISE:- Whirlpool is a very quiet machine if put in sleep mode & low settings. However, when you set it in a higher setting – it will make a progressive louder hum (it is not an annoying noise…….it is more like white noise)

It stands at 22-inches tall – you can place it in the corner of the room and let it do its job.  It uses two filters; (1) Carbon activated pre-filter which should be changed after a period of 6-8 months depending on usage and (2) HEPA filter which should be replaced after a period of 1.5 years – still basing on usage.



 (1) At first, it combines its pre-filter and charcoal filter to capture all large particles in the air and these might include particles like dust and lint. The same combination of filters helps in destroying common household odors like cooking smoke, fireplace smoke and tobacco smoke.  (2) In the second phase, a True HEPA filter captures 99.97% of all airborne particles as small as 0.3 microns in size – these might include;  dust mites, debris, mold spores, plant pollen, and pet dander. (The main reason why doctors recommend HEPA filters is because they reduce exposure to indoor asthma triggers like dust and pet dander) – so if you’re searching for a good air purifier for dust, allergies, pets and smoke – look no further than this because GermGuard was tailored for just that.

There are a few things that you can do to reduce on the dust and other related pollutants in your room, house and office.


  • Clean your room often:- If it is a bedroom, wash all bed sheets at the end of the week – you can use hot water of about 130F. If it is your living room, vacuum the sofas at least twice a week if you don’t have pets. But those with pets, you need to vacuum those sofas on a daily basis. Pets drop off far on a daily basis and most of it finds its way into the sofa.


  • Get rid of Dust Mite Hangouts: – We all love drapes in our homes but they’re good at hiding dust mites. So if possible you can replace them with wooden blinds. Also opt for hard floors rather than carpets and rugs – these trap dust and related allergens.


  • Avoid Cleaning Your Room Late In The Evening:- Sounds wired but true. When you clean the room in the evening, it will take 2 hours or more for the dust to settle. You will have very few hours if not minutes to be outside of your house/room – so you will settle down before the dust settles down after a clean. Always clean your room in the morning so that dust gets enough time to settle before you’re back home.


  • If Possible – Keep Pets Out Of The Room:- It could be your bedroom, living room or office – but any sort of room where you spend most of your time. The dander in your pet’s fur can trigger off various allergic conditions (making it hard to breathe). The same dander can track in pollen & mold from outdoors.


  • Let go of fluff: – There is no need of keeping extra pillows, stuffed animal toys, linens and other dust collecting objects in your room. The less congested the room, the less dust in it.
