We all love our pets, but with that comes pet dander. Pet dander is a collection of microscopic particles from dead skin and fur shed by cats, dogs, rodents and other animals in the home. So does vacuuming remove pet dander?

The answer is yes! Vacuums are an effective tool for removing pet dander from carpets and furniture. To ensure maximum effectiveness when it comes to cleaning up after your furry friends, there are certain features you should look out for in a vacuum cleaner as well as some tips on how to effectively use it.

In this post we will discuss what exactly pet dander is and how to reduce its presence in your home environment. In addition we review the benefits of using vacuums specifically designed for removal of pet hair and debris such as dust mites or pollen particles as well as animal allergens.

What is Pet Dander?

Pet dander is a type of allergen that can cause allergic reactions in humans. It consists of tiny particles, usually less than 10 microns in size, which are shed from the skin and fur of cats, dogs, rodents, birds and other animals with fur or feathers. These particles contain proteins that can trigger an allergic reaction when inhaled by people who are sensitive to them.

Definition of Pet Dander

Pet dander is made up of microscopic flakes of dead skin cells that have been shed from the bodies of pets such as cats and dogs. The particles are so small they cannot be seen with the naked eye but can still cause allergies if inhaled by someone who is sensitive to them.

Sources Of Pet Dander

The main source for pet dander comes from our furry friends themselves – their saliva, urine and sweat glands secrete proteins into their fur which become airborne when they move around or groom themselves. Other sources include carpets and furniture where pet hair has accumulated over time; even after vacuuming these areas may still contain some allergens due to the tiny size of pet dander particles.

Pet dander Particle Size Distribution

Understanding the particle size distribution of pet dander can help you choose the right vacuum cleaner for your home. The majority of pet dander particles measure between 0.5 to 5 microns in diameter – about one-tenth the width of a human hair. However, it can be as small as 0.1 microns in diameter!

Particles this small are difficult to filter out using traditional vacuums because they easily pass through their filters without being captured.

Health Effects Of Pet Dander

Exposure to pet dander can cause symptoms ranging from mild irritation (sneezing) to more severe respiratory issues such as asthma attacks or difficulty breathing in those who suffer from allergies or asthma triggered by animal allergens. People with weakened immune systems may also experience more serious reactions such as hives or anaphylaxis shock upon exposure to high levels of pet dander in enclosed spaces like homes or cars where air circulation is limited

Key Takeaway: Pet dander is a type of allergen that can cause allergic reactions in humans and consists of tiny particles shed from the skin and fur of cats, dogs, rodents, birds and other animals with fur or feathers. Sources include pets themselves as well as carpets and furniture; exposure to pet dander can lead to mild irritation (sneezing) to more severe respiratory issues such as asthma attacks.

How to Reduce Pet Dander in the Home?

Vacuuming Regularly: Vacuuming regularly is one of the most effective ways to reduce pet dander in your home. It helps to remove pet hair, dirt, and other debris that can accumulate on carpets and rugs.

To get the best results, use a vacuum cleaner with strong suction power and brushrolls designed for deep cleaning carpets. You should also empty the dustbin after each use to prevent it from becoming clogged with pet hair or dander.

Cleaning Surfaces and Upholstery: Pet dander can also accumulate on surfaces such as furniture, curtains, bedding, and clothing. To reduce this buildup of allergens in your home environment, you should clean these items regularly using a damp cloth or vacuum attachment tool specifically designed for upholstery cleaning.

Using air purifiers and humidifiers can be an effective way to reduce airborne particles like pet dander that can cause allergies or asthma symptoms when inhaled by people sensitive to them.

Look for air purifiers equipped with HEPA filters, which are proven to be highly efficient at capturing small particles such as pollen or animal fur from the air inside your home environment. Additionally, using a humidifier will help keep indoor air moist, preventing dryness which can worsen allergy symptoms caused by exposure to pet dander indoors.

What Features Should You Look for in a Vacuum Cleaner for Removing Pet Dander?

When selecting a vacuum cleaner for removing pet dander, there are several important features to consider.

  • Suction power and brushrolls are essential for deep cleaning carpets and rugs, while tool attachments and accessories make it easier to clean hard-to-reach areas like stairs or furniture.
  • A HEPA filtration system is also necessary for trapping allergens like pet dander in the vacuum bag or canister. This should be combined with a sealed system design to prevent allergens from escaping back into the air during vacuuming.

Suction power and brushrolls

These are two of the most important features when looking for a vacuum cleaner designed to remove pet dander. Vacuum cleaners with higher suction power will be able to lift more dirt from carpets and rugs than those with lower suction power. Furthermore, brushrolls help agitate carpet fibers so that more dirt can be lifted out by the suction of the vacuum cleaner.

Additionally, look for models with adjustable speed settings so you can adjust them depending on your floor type—carpeted floors require higher speeds while bare floors need lower speeds to avoid damaging delicate surfaces like wood or tile floors.

Tool attachments and accessories are also useful when it comes to removing pet dander from hard-to-reach places such as stairs or furniture upholstery. Many modern vacuums come equipped with tools specifically designed for these types of tasks, such as crevice tools, dusting brushes, and upholstery nozzles. These allow you to easily reach tight corners where pet hair tends to accumulate over time without having to move large pieces of furniture around your home every time you want to do some cleaning.

HEPA Filtration System

A HEPA filtration system is another key feature when looking at vacuums designed specifically for removing pet dander from your home environment. HEPA stands for High Efficiency Particulate Air filter, which traps particles down to 0.3 microns in size – meaning that even the smallest of pet dander particles will be captured by these filters before being released back into your home’s air supply again.

In our recent review of the Dyson V15 Detect Absolute we discovered that it goes even further than HEPA standards. Its whole-machine HEPA filtration system traps 99.97 per cent of microscopic particles as small as 0.1 microns! As a result the Dyson V15 excels at capturing every last bit of pet dander because it can be as small as 0.1 microns in size.

Look for models that have either washable/replaceable filters (which should be cleaned regularly) or disposable bags (which should be changed often).

Why you need a completely sealed system

Vacuum cleaners that are designed as a completely sealed system further reduce allergen exposure, by preventing any trapped particles from being released back into the air during operation. This vacuum feature is essential if someone in your household suffers from allergies. It means the entire airflow route through the vacuum is properly sealed, to prevent dirty air from bypassing the filter.

Most cheap vacuums do not have such a system and leak micro particles of collected back out into the home through poorly constructed seals. Premium vacuums like those from Miele and Dyson have completely sealed systems to ensure that all of the dirt that is picked up, including the micro particles, does not escape.

  • Miele vacuums have an AirClean Sealed System®;
  • Dyson vacuums feature a whole-machine HEPA filtration system.

Also, if a vacuum cleaner is claimed to have a completely sealed system, you should check what testing standard the system is built to (or if it is even built to a recognised standard at all). 

For example, whilst researching where Dyson Vacuums are made, we discovered that they are tested to meet the ASTM standards F3150 as well as EN 60312 and EN1822. Similarly, Miele vacuums' filtration system is tested by TUV Nord to meet EN60312 standards in Germany where Miele vacuums are made.

Other Considerations

Finally, consider other features such as cord length (or consider a cordless vs corded vacuum for added convenience), noise level (if sound sensitivity is an issue), weight (for portability), and ease of use/maintenance (especially if elderly people will be using it) before making a final decision on which model best suits your needs. 

Key Takeaway: When selecting a vacuum cleaner for removing pet dander, look for models with adjustable suction power and brushrolls, tool attachments and accessories, HEPA filtration system, sealed system design, cord length, noise level, weight and ease of usemaintenance.
