When summer rolls around, abundant warmth comes, and, unfortunately for many, peak allergy season gets in full swing. Pollen counts soar, mold spores rise, and indoor air quality issues can trigger allergy attacks. Though medication and cleanup help, your HVAC system is one of the most powerful tools in your allergy-fighting arsenal. More specifically, it is your air filter.
At Mend Services in Buda, TX, we understand how crucial water and indoor air quality is, especially for those struggling with seasonal allergies or immunosensitivity. Choosing the right air filter can reduce the severity of symptoms. This guide can help you understand how to breathe more easily in your home.
Why Air Filters Matter More in Summer
During summer, allergens like grass pollen, mold spores, and pet dander circulate more aggressively. Your air filter is the first line of defense against allergens. A high-quality air filter traps airborne particles that can irritate your upper respiratory system. These particles can trigger sneezing, itchy eyes, wheezing, and worsened asthma symptoms.
Not all HVAC filters are the same. Some capture larger particles like dust, while others can trap microscopic irritants like dust mites or dander.
Understanding MERV Ratings
When comparing air filters, one of the first things you need to know is the MERV rating. MERV stands for Minimum Efficiency Reporting Value. The scale ranges from 1 to 20. The higher the number, the more effective the filter is at filtering and trapping smaller particles.
MERV 1-4
These are basic filters that capture larger particles like dust and lint. They are not suitable for allergy sufferers.
MERV 5-8
These filters are commonly found in residential systems. They can capture mold and pet dander but will likely miss smaller allergens.
MERV 9-12
These filters offer a better option for allergen filtration. They filter fine particles like pollen and some bacteria.
MERV 13-16
These filters are ideal for allergy sufferers. They trap tiny particles, including viruses. However, as a word of caution, most modern HVAC systems can handle MERV 13 filters, but not all can. It is essential to get advice from a professional.
MERV 17-20
Hospitals often use these filters to protect against the spread of bacteria and viruses. They may not be compatible with residential systems.
If allergies are a concern, we recommend aiming for a MERV rating between 11 and 13. These filters perfectly balance high-level filtration with proper airflow compatibility for most Buda homes.
Understanding the Types of Filters
Multiple filters are available, but not all are allergen-specific or compatible with all HVAC systems. Professional guidance can help you choose.
Fiberglass filters are inexpensive but only capture large particles like dust. Although they protect HVAC components, they will not improve indoor air quality much.
Pleated filters offer more surface area for trapping particles, including allergens. Although slightly more expensive than fiberglass, they provide good airflow without restriction.
Electrostatic filters use static electricity to attract and trap particles. There are both washable and disposable options. The main drawback is that the effectiveness can vary widely, depending on the manufacturer. These filters work well for those with light allergies.
HEPA filters are the gold standard for homes with allergy sufferers. They are incredibly efficient, capturing around 99.97% of particles 0.3 microns or larger. For comparison, a single grain of sand can be over 800 microns. However, most residential systems cannot handle HEPA filters in place of typical filters; HEPA ones will reduce airflow too much, which can cause many problems. Instead, you may need a specialized whole-home air purification system.
Summer Allergens to Watch For
Knowing the allergens you are up against can help you win the fight. It can also help you choose the best HVAC filter for trapping the offenders.
Grass Pollen
Grass pollen is one of the leading causes of hay fever. It is light and easily blown indoors or brought in on clothing and shoes.
Mold Spores
Mold spores thrive in warm, moist environments. With summer’s increased heat and humidity, those with mold allergies often begin to suffer. Mold spores can be airborne and populate surfaces inside and outdoors.
Pet Dander
Dogs and cats often begin to shed more and produce more dander in the summer. Exposure to this microscopic allergen can wreak havoc on a sufferer’s respiratory system.
Dust Mites
Dust mites multiply faster in warmer months. They live on bedding, furniture, and carpeting.
A quality air filter can help reduce these allergens inside your home, helping you breathe easier. These filters can create a cleaner and safer indoor environment.
Filter Maintenance Matters
Even the best air filter cannot properly filter the air if it’s clogged. You may need to change or clean your filter more frequently during the summer.
How Often Should You Change Your Filter?
Filter manufacturers provide recommendations for the frequency of changes. These instructions serve as a guide to help you stay on track with filter changes.
- Basic fiberglass: Every 30 days
- Pleated: Every 60-90 days
- HEPA and Electrostatic: Every 6-12 months
If you have pets, smoke, or live in an area with high pollen counts, check your filter more often. A clean filter increases system efficiency, reduces energy costs, and improves allergy symptoms.
Matching the Filter to Your HVAC System
We recommend checking your owner’s manual for recommended MERV ratings. You should also consult with one of our expert HVAC technicians to receive professional guidance. If your current HVAC system cannot handle HEPA filters, there are other options for relief, including air purifiers.
Room-Specific Solutions
For severe allergy symptoms, you may also need room-specific filtration. For instance, bedrooms may benefit from portable air purifiers with HEPA filters.
Additional Ways to Improve Allergy Symptoms
While choosing the right filter is critical, other ways exist to create a healthier indoor space. Consider these options for reducing allergy attack risks.
Keep Windows Closed
Many allergists recommend keeping your windows closed on high-pollen days. Opening your windows can expose you to more pollen inside the home and further exacerbate allergy symptoms.
Use a Dehumidifier
A dehumidifier can help control the moisture levels in your home. Reducing humidity can help prevent mold growth.
Vacuum Regularly
Vacuum regularly and ensure you use a vacuum with a HEPA filter. Vacuum all carpeting and furniture.
Wash Bedding
You should wash your bedding weekly in hot water to kill dust mites. They reproduce rapidly; a female can lay up to 20 eggs daily.
Groom Pets
It is also essential to regularly wash pets and brush them to reduce shedding and dander. Ask your vet for guidance on selecting the right shampoo for your dog or cat.
