Where to buy Vent Axia MVHR replacement filters
You can purchase Vent Axia MVHR replacement filters from several types of places in the UK. Specialist HVAC and ventilation suppliers often stock or can order the correct filters for your unit. Many also sell online, making it easier to compare prices and delivery times. Using suppliers who focus on ventilation systems ensures you get the right product rather than a generic substitute.
Direct purchases from Vent Axia’s official website or authorised distributors provide the most reliable source for genuine filters. You will need your MVHR unit’s exact model number to identify the compatible filter range. This avoids the risk of buying the wrong size or grade, which can reduce ventilation efficiency or damage the system.
Some general DIY and home improvement websites offer Vent Axia filters but often only the most common sizes and grades. These can be convenient but may lack specialist advice or exact part options. Local builders’ merchants rarely stock these filters due to niche demand, so online ordering is usually more practical.
- Specialist UK HVAC suppliers: wide stock, expert advice
- Vent Axia official distributors: guaranteed genuine parts
- Online retailers: convenience but limited range
- Local merchants: usually do not stock Vent Axia filters
How to confirm the correct filter grade for your Vent Axia MVHR
Vent Axia MVHR systems commonly use filters graded G3 (coarse) or G4 (fine) as per European standard EN 779:2012. Your system’s manual or the filter housing label usually states the required grade and dimensions in millimetres. Always check these details before buying replacements. We go through washable mesh filter for extractor fan step by step elsewhere on the site.
Matching filter dimensions (width, height, and thickness) is critical. Even a small mismatch of a few millimetres can prevent proper sealing or airflow, compromising the ventilation performance. If your unit’s manual is missing, the model number lets you search Vent Axia’s website or contact their support for filter specs.
If your home has specific needs like allergies or very dusty surroundings, a higher-grade filter such as a HEPA filter might be considered, but these are not standard in Vent Axia MVHR and require verifying compatibility carefully. In most cases, standard G3/G4 filters suffice.
- Check MVHR manual or unit label for filter grade and size
- Use exact dimensions to avoid airflow issues
- Contact Vent Axia support if uncertain
- HEPA filters need compatibility check and are not standard
Typical cost range for Vent Axia MVHR replacement filters
Vent Axia MVHR replacement filters generally cost between £15 and £40 each in the UK, depending on the filter’s size and grade. Smaller, standard G3 filters tend to be at the lower end of this range, while larger or finer grade G4 filters approach the higher end. Before you commit to anything, it is worth looking at how to improve indoor air quality.
HEPA filters, due to their finer filtration and rarity for MVHR systems, typically cost more—often exceeding £50 per filter. These prices reflect the complexity and materials involved, plus their limited availability.
Filter lifespan usually ranges from 6 to 12 months based on usage and indoor air quality. More frequent replacement may be needed in dusty environments to maintain healthy ventilation and system efficiency, adding to the annual cost.
| Filter Type | Typical Size Range (mm) | Cost Range (£) | Lifespan (months) |
|---|---|---|---|
| G3 Coarse | 190x190x20 to 300x300x20 | 15-25 | 6-12 |
| G4 Fine | 190x190x20 to 300x300x20 | 25-40 | 6-12 |
| HEPA (rare) | Varies, usually smaller | 50+ | 6 or fewer |
Using HEPA filters in dusty environments with Vent Axia MVHR units
HEPA filters can trap particles down to 0.3 microns, making them highly effective in very dusty homes or for occupants with allergies. However, Vent Axia MVHR units are primarily designed for standard G3 or G4 filters. Installing a HEPA filter usually means increased airflow resistance. It helps to understand ventilation piv or mvhr for condensation before going further.
This higher resistance often requires the MVHR fan to work harder, increasing energy use and potentially shortening the unit’s lifespan. Not all Vent Axia units are designed to handle HEPA filters, and adding them can void warranties or cause system failure if the fan cannot compensate.
If your home suffers from unusually heavy dust or allergens, consult Vent Axia or a ventilation specialist before upgrading to HEPA filters. Sometimes a pre-filter combined with regular maintenance gives a better balance between air quality and system performance.
- Superior filtration for allergens and fine dust
- Can improve indoor air quality in problem environments
- Increased fan energy use and noise
- Potential incompatibility with MVHR unit
- Higher cost and more frequent replacements
Steps to identify, buy, and replace Vent Axia MVHR filters safely
Replacing Vent Axia MVHR filters involves a few clear steps to maintain airflow and indoor air quality. Start by turning off the MVHR unit to avoid dust being blown during filter change.
Locate the filter access panel, usually on the unit’s side, and remove the old filters carefully to avoid dispersing trapped dust into the room. Dispose of used filters per local waste guidelines.
Compare the dimensions and grade of the old filters with Vent Axia’s specifications for your model. Purchase replacements from a reputable supplier using the confirmed part numbers.
Install the new filters with correct orientation, ensuring a tight, secure fit to avoid air bypass. Close the panel and restart the MVHR unit, checking for normal airflow and noise.
- Turn off MVHR unit and isolate power if needed
- Open filter access and remove old filters gently
- Check filter dimensions and grade against your unit specification
- Buy correct replacement filters from a trusted supplier
- Install new filters correctly and secure access panel
- Restart unit and verify normal operation
Vent Axia MVHR replacement filters where to buy: summary and advice
Buying Vent Axia MVHR replacement filters requires confirming your unit’s model and the correct filter grade—usually G3 or G4. Trusted UK HVAC suppliers and Vent Axia’s authorised distributors provide reliable sources, while some online retailers offer convenience for common sizes.
Expect to pay £15-£40 per filter depending on size and filter type, with HEPA filters costing significantly more and needing compatibility checks due to high airflow resistance. Regular replacement every 6-12 months keeps your system efficient and your home air healthy.
Don’t guess on filter grades or sizes; incorrect filters can reduce airflow, increase costs, or damage your MVHR. If your home faces heavy dust or allergens, consult professionals before choosing HEPA options to avoid unintended consequences.
Questions people still ask
Can I use generic filters instead of Vent Axia branded ones?
Generic filters might fit dimensionally but may lack the correct filtration grade or quality. Using them risks poor air quality and possibly damaging the MVHR system. Always match filter specifications exactly.
How often should I replace Vent Axia MVHR filters in a dusty environment?
In dusty homes, replacing filters every 3-6 months is advisable to maintain airflow and filtration efficiency. Standard replacement is 6-12 months for average dust levels.
Is it worth upgrading to HEPA filters for MVHR in the UK?
HEPA filters offer superior particle removal but increase fan load and energy usage. For most UK homes, standard filters suffice unless there is severe dust or allergy risk.
Where do I find my Vent Axia MVHR unit’s model number?
Check the unit’s inside access panel or the original installation paperwork. The label shows model and serial numbers needed to order correct filters.
Do Vent Axia filters qualify for any UK green home grants or schemes?
Filters themselves typically do not qualify, but maintaining your MVHR system can improve EPC ratings and support eligibility for schemes like ECO4 by ensuring ventilation efficiency.
