As a filter becomes more clogged with dust and other particles, the appliance has to work harder to promote airflow.
Dirty Air Filters Reduce Airflow, Increasing Strain on Your Blower Fan. Blower fans are designed to push air through the filter. If the filter becomes too clogged with dust, dander and debris, then the blower has to struggle harder to pass the air through the blocked filter.
Not changing the filter will impact the performance of the air purifier. It will not be able to purify the air in or your home or I can say it will make it worse. Also, the filter will become home to harmful microorganisms that will impact your health.
It is recommended that you clean your water-based air purifier every 3-4 weeks to ensure optimal performance. You should also replace the water filter and the activated carbon filter every 6-12 months, depending on your use.
If you don't change your AC filter, it will begin to fail. It will no longer be able to filter the air properly, letting dust and contaminants get into the HVAC system. Dust jams the moving parts of an AC such as fan motors and valves.
Unkempt air filters may negatively affect indoor air quality by spreading pet dander, dust, and other allergens throughout your home. This may lead to irritated eyes, nose, and potentially breathing problems.
A clogged filter is not just bad news for energy costs but also for the health of your family. Old filters circulate poor quality air indoors. This means you and your family are forced to inhale air filled with allergens.
If you let this happen for long enough, the filter could break, releasing all of the pollutants it has accumulated. The pollutants will then float freely though your HVAC system, your house, and eventually your lungs. This can lead to your home's air supply feeling stuffy and dirty, and you could get sick as a result.
It's advised to keep your air purifier turned on all day and night, even when you're sleeping or not at home. Many people think that switching it off during the night or when they're not present is a logical energy-saving measure, but it is recommended to keep it running constantly.
Wash your HEPA filter with warm water and allow it to dry if your model specifically states that water cleaning is safe. You can also soak your filter in hot water if it is extremely dirty. Clean non-washable, permanent HEPA filters using a vacuum to remove dust and debris.
By positioning the air purifier near your bed, you can create a localized zone of cleaner air, which can be especially comforting for those with respiratory conditions. Ensure that the air purifier is placed at a safe distance from your head to avoid direct air exposure during sleep.
Most air purifiers have a pre-filter, HEPA filter, and sometimes an activated carbon filter. You can wash, dry and reuse most pre-filters and carbon filters, but you'll need to buy a replacement HEPA filter from time to time.
The lifespan of an air purifier can vary depending on several factors, including the quality of the device, frequency of use, maintenance, and the type of filtration system it employs. On average, air purifiers can last between 5 to 10 years.
Is no AC filter better than a dirty one? No. A dirty filter will slightly protect against some dust particles that will damage your AC system. Its better to have a dirty filter than having no filter.
Typically, a high-quality air purifier like those from Alen can start showing noticeable air quality improvements within 30 to 60 minutes. However, achieving optimal results throughout your entire space can take several hours, depending on the conditions.
Clogging up your energy budget
This wastes energy and adds to your utility bills. Heating and air conditioning make up nearly half of the energy costs in a typical U.S. home. A clogged filter causes those systems to use 15 percent more energy, according to the U.S. Department of Energy.
Regardless of where you live, the good news is, air purifiers do not use a lot of electricity to operate.
What are the downsides of air purifiers? There aren't a lot of downsides to having an air purifier in your home aside from the financial investment. Many ionizers, especially older models, can generate ozone when they are operating, which is known to exacerbate asthma.
Ensure your air purifier has enough clearance around it to function optimally. Avoid placing it behind furniture or in tight corners where airflow might be restricted. Ideally, there should be at least 3-5 feet of clear space around the unit to allow for unimpeded air intake and output.
"Air filters can become clogged with particles like dust, pet dander, and allergens, reducing airflow and causing the purifier to work harder, which may lead to increased energy consumption and shortened device lifespan."
Poor Air Quality
If the filter is too dirty to do its job, those unwanted particles can collect in your ductwork and cling to the internal components of your HVAC system, ultimately diminishing air quality throughout your house.
How Do I Know if My Air Purifier Filter is Dirty? First, take a look at the filter. If it appears grey or black with dust and debris, then it's time for cleaning or a change depending on the type of filter. Another sign that your air purifier filter is dirty is the reduced efficiency of the purifier.
You or your family may experience the following symptoms from a dirty air filter or air ducts: Respiratory infections. Worsened allergies or asthma. Frequent sinus infections.
Why does it need to be replaced? If the HEPA filter loses its efficiency, then the contaminants that you are vacuuming will be exhausted back into the air. These contaminants, no longer stuck to a surface but are now floating in the air can now be respirable depending on their size.
You may notice a significant decline in HVAC performance, increased energy bills, and decreased comfort in your home. Additionally, delaying filter changes can lead to more extensive damage to your HVAC system, requiring costly repairs or replacement.
