Why 15x35x1 air filter selection matters

90 percent. That's how much of their time the average person spends indoors, according to data from the Environmental Protection Agency.

Noting this, it's crucial to prioritize the quality of the air you and your family breathe. Air filters are a big part of maintaining quality indoor air. High-end, properly sized 1-inch air filters effectively capture dust, pollen, mold spores, pet dander and other airborne particles, preventing them from circulating throughout properties and promoting a healthier overall indoor environment.

Proper 15x35x1 air filters also allow your system to run more effectively and can help reduce the overall workload on your furnace and cooling system. This can help reduce your home's heating and cooling costs and the frequency of HVAC system repairs.

This post serves as a guide to your air filter buying needs. It covers everything from your MERV options to the various types of efficient air filters, and cost and value analysis for replacements. Read on to learn more.

Common mistakes when choosing 15x35x1 air filters

First, let's cover some of the common mistakes that property owners make when selecting 15x35x1 air filters. These include:

Ignoring the MERV rating

MERV stands for "minimum efficiency reporting value" and indicates a filter's ability to trap particles. Choosing a filter with a low MERV can result in less particle capture, while filters with high MERVs capture more, but they may also restrict airflow. It's best practice to select a MERV rating that balances your property's air quality needs with its HVAC system requirements and capabilities.

There is no universal MERV rating. Instead, consider selecting a 15x35x1 air filter that reflects the level of particle capture you're looking to attain. The filter you select should consider your HVAC system and household factors, such as pets, allergies, smoking, typical dust levels and the surrounding environment.

Weighing cost vs. quality

Many property owners choose low prices over quality and performance. However, when it comes to air filters, you often get what you pay for. Cheaper filters may not effectively trap particles and pollutants, which can result in poor overall air quality throughout the property. Avoid this pitfall by selecting the 15x35x1 air filter that combines your required filtration quality level without being overly restrictive on your HVAC system.

It's also important to note that not all brands are created equal. For best results, make sure you're using filters from a brand that prioritizes quality and construction.

Poor replacement timing

The industry standard is to replace your 15x35x1 air filter every 90 days for average households or as often as 60 days for homes with pets or indoor smokers. Households with individuals sensitive to allergens should change their 15x35x1 air filters as often as every 6 weeks. Waiting too long for a replacement can lead to soiled filters that restrict air flow, causing excess wear and tear on your HVAC system and increasing your utility bills. Many property owners also mistakenly change their air filters too soon, which creates an unnecessary — and easily avoidable — expense.

Understanding your MERV options for 15x35x1 air filters

MERV is an industry-standard rating system that measures the efficiency of a 15x35x1 air filter in capturing particle matter. It is based on a scale from 1 to 20. The higher the rating, the better the filter is at capturing particles — and vice versa. Low MERV filters aren't able to capture many fine particles, while high-efficiency HEPA filters can capture 99.97 percent of particles at or around 0.3 microns in size.

Yet, a higher MERV isn't always better for your home or HVAC system. It's important to match the MERV rating to your specific household needs and your HVAC system's capability. Check the recommended MERV rating in your specific HVAC system owner's manual to ensure compatibility and balance it with any unique household requirements.

Here's an overview of the most commonly used MERV ratings for 15x35x1 air filters that are also offered by Filter King:

  • MERV 8 air filters: Offer basic filtration and high airflow. MERV 8 15x35x1 air filters tend to be system-friendly.
  • MERV 11 air filters: Offer a more balanced filtration performance for most homes.
  • MERV 13 air filters: High-efficiency filters that offer superior filtration performance and are often the preferred choice for homes with individuals who are sensitive to allergens.
  • MERV 8 Carbon (Odor Eliminator) air filters: MERV 8 rating air filters that also include a carbon layer to help reduce odors.

Types of air filters: why we use pleated design

Choosing the right air filter isn't as easy as it may seem. From fiberglass filters to pleated filters, HEPA filters and carbon models, and even washable, reusable filters, the best air filter for your household depends on your specific needs and your cooling and heating unit's requirements.

Pleated filters tend to offer the ideal balance that suits most requirements and residential HVAC systems. They are typically made from cotton or polyester material and feature a large, folded filter frame to capture particles and promote cleaner air throughout a property. These larger accordion-style pleats are designed to capture more particles without restricting airflow. Aside from maximum filtration, pleated filters also tend to have longer lifespans and are more cost-effective.

Health and air quality benefits of proper 15x35x1 filter selection

Air filter size matters for improving indoor air quality and maximizing health benefits. Here's a look at some of the key health benefits your household can experience by finding the right 15x35x1 filter:

  • Improved respiratory health: Proper 15x35x1 filters remove fine particles, allowing your family to breathe healthier.
  • Reduced allergy symptoms: Removing smaller particles helps prevent reactions in anyone who's more sensitive to allergens. Typically, the right 15x35x1 filters help prevent the circulation of allergens that can cause stuffy and runny noses, watery eyes, sneezing, coughing, shortness of breath and more.
  • Protection from dust mites and pet dander: Air filters incorrectly sized won't capture all contaminants, including allergens like dust mites and pet dander. These allergens have the potential to trigger more severe reactions, such as eczema and chronic allergy symptoms, like sinus infections and asthma attacks. Choosing the correct size air filter can be the difference.

Above all, selecting filters that fit properly helps improve your property's indoor air quality by removing airborne contaminants and particles. This directly results in a cleaner and more hygienic overall environment.

Best 15x35x1 air filters by household needs

What's the best 15x35x1 air filter that meets your household needs and suits your HVAC system?

Typically, a single-family home should look for a MERV 8 or MERV 11 15x35x1 air filter. MERV 8 air filters are ideal for capturing general dust and pollen, while MERV 11 filters offer better filtration in residential HVAC systems and can capture smaller particles like pet dander and mold spores.

If your household members are sensitive to allergens, consider a MERV 13 15x35x1 air filter. These filters are highly effective at trapping even the smallest airborne particles, such as pollen, dust, smoke, mold, bacteria and more.

If your home has odor concerns, consider a MERV 13 15x35x1 air filter or a MERV 8 15x35x1 carbon air filter. These filters are ideal for high-dust environments or households with smokers. MERV 8 carbon filters are specifically designed to help eliminate odors, such as those from pets, cooking, smoke or other household chemicals.

Cost and value analysis for 15x35x1 replacement filters

Filters with higher MERV ratings tend to cost more than those with lower ratings because they're built with thicker material and designed to be more efficient in capturing small particles to improve your home's indoor air.

Price is directly tied to the filter efficiency in capturing microscopic particles and allergens, thereby reducing indoor air pollution. This higher comparative upfront cost is often offset by health benefits and HVAC equipment efficiency.

When it's time to change your existing filter, you have options. While many property owners elect to purchase air filters on an as-needed basis, you can save significantly on bulk purchases due to volume discounts from lower per-unit prices. This provides more than just a cost savings benefit, but also ensures that you won't run out of air filters when it's time for replacement.

Since it's best practice to change air filters regularly, opting into a subscription plan is another option that can make it easy and convenient for property owners. Filter King offers bulk purchasing and subscription options upon checkout to help you save on 15x35x1 high efficiency air filters.

Making your decision: what you need to know

Ready to purchase a new high efficiency air filter? Here's what you need to know before selecting a replacement:

  • Your property's filtration needs and MERV rating. Remember, the higher MERV ratings mean the filter is more effective at capturing particles.
  • Should you upgrade from basic to more premium filter options? While MERV 8 filters are ideal for most single-family households, MERV 11 and 13 filters work harder to protect more sensitive households from allergens.
  • Budget considerations: While better-quality 15x35x1 air filters typically have a higher upfront cost, the long-term benefits often make up for it with better household health and the potential to reduce medical expenses. Make sure you know the true return on investment with your filter selection.

Next steps after choosing your air filter

After you've selected the right filter, consider arranging an automatic delivery schedule to ensure you always have a new filter on hand when it's time to change it out.

You should also monitor your filter's performance and adjust as necessary according to your household's needs and HVAC filter requirements. Consider tracking air quality and reassessing MERV choice as necessary. Finally, don't discount seasonal changes that could impact your filter choice. For instance, you might select a high MERV 15x35x1 filter or HEPA filter in the spring and summer when pollen counts are high.

Frequently Asked Questions (FAQs)

How often should I replace my 15x35x1 air filter?

You should replace most 15x35x1 air filters every 30 to 90 days depending on your specific needs and circumstances. In households with asthma or allergies, replace your air filter every 6 weeks. If you have pets, replace it every 2 months. If you have young children, replace it every 2 to 3 months.

What happens if I use the wrong size air filter?

Using the wrong size air filter can lead to poorer air quality and cause problems for your HVAC system. If the air filter size is too small, unfiltered air can bypass the filter and allow for dust to enter your HVAC system.

Can I cut a larger filter to fit my 15x35x1 filter slot?

No, never cut air filters to fit your filter slot if you’ve ordered the wrong size. Cutting damages the filter frame and media, creates gaps for air bypass, and reduces filtration effectiveness. If you've ordered the wrong size, Filter King offers a 30-day money back guarantee, so you can easily return or exchange your filter for the correct size.

Are expensive 15x35x1 air filters worth the extra cost?

In many cases it may be worth the extra cost, although it largely depends on your specific needs and circumstances. Higher-quality 15x35x1 filters often provide better filtration, last longer, and protect your HVAC system more effectively, meaning that the investment pays off through better air quality and reduced system maintenance costs.

Can I run my HVAC system without a 15x35x1 filter temporarily?

No, never run your HVAC system without a filter, even temporarily. Running it without a filter allows dust, debris, and particles to enter your system, which can lead to expensive damage to components like the blower motor and evaporator coils.

Will a MERV 13 15x35x1 filter restrict airflow too much?

A MERV 13 15x35x1 filter may restrict airflow in some of the older or lower-capacity HVAC systems, while most modern residential systems should handle a MERV filter without issues. If you notice reduced airflow, longer heating/cooling cycles, or increased energy bills after installing a MERV 13 filter, consider changing to a MERV 11 instead.
